BACKGROUND

Analyte monitoring devices have been used as medical diagnostic devicesto determine a level of analyte from a sample. One common application isglucose measurements. For example, an analyte monitoring device is usedwith a remote sensor to perform an analyte reading. The sensor may beconfigured for implantation (e.g., subcutaneous, venous, or arterialimplantation) into a patient. The analyte monitoring device processessignals from the remote sensor to determine the concentration or levelof analyte in the subcutaneous tissue and may display the current levelof the analyte.

DETAILED DESCRIPTION

Before the present inventions are described, it is to be understood thatthis invention is not limited to particular aspects described, as suchmay, of course, vary. It is also to be understood that the terminologyused herein is for the purpose of describing particular aspects only,and is not intended to be limiting, since the scope of the presentinvention will be limited only by the appended claims.

Where a range of values is provided, it is understood that eachintervening value, to the tenth of the unit of the lower limit unlessthe context clearly dictates otherwise, between the upper and lowerlimits of that range is also specifically disclosed. Each smaller rangebetween any stated value or intervening value in a stated range and anyother stated or intervening value in that stated range is encompassedwithin the invention. The upper and lower limits of these smaller rangesmay independently be included or excluded in the range, and each rangewhere either, neither or both limits are included in the smaller rangesis also encompassed within the invention, subject to any specificallyexcluded limit in the stated range. Where the stated range includes oneor both of the limits, ranges excluding either or both of those includedlimits are also included in the invention.

Unless defined otherwise, all technical and scientific terms used hereinhave the same meaning as commonly understood by one of ordinary skill inthe art to which this invention belongs. Although any methods andmaterials similar or equivalent to those described herein can be used inthe practice or testing of the present invention, some potential andpreferred methods and materials are now described. All publicationsmentioned herein are incorporated herein by reference to disclose anddescribe the methods and/or materials in connection with which thepublications are cited. It is understood that the present disclosuresupersedes any disclosure of an incorporated publication to the extentthere is a contradiction.

It must be noted that as used herein and in the appended claims, thesingular forms “a”, “an”, and “the” include plural referents unless thecontext clearly dictates otherwise. Thus, for example, reference to “aprogram update” includes a plurality of such program updates andreference to “the program update” includes reference to one or moreprogram updates and equivalents thereof known to those skilled in theart, and so forth.

Generally, embodiments of the present disclosure relate to in vivomethods and devices for detecting at least one analyte such as glucosein body fluid. Accordingly, embodiments include in vivo analyte sensorsconfigured so that at least a portion of the sensor is positioned in thebody of a user (e.g., within the ISF), to obtain information about atleast one analyte of the body, e.g., transcutaneously positioned inuser's body. In certain embodiments, an in vivo analyte sensor iscoupled to an electronics unit that is maintained on the body of theuser such as on a skin surface, where such coupling provides on body, invivo analyte sensor electronics assemblies.

In certain embodiments, analyte information is communicated from a firstdevice such as an on body electronics unit to a second analytemonitoring device which may include user interface features, including adisplay, and/or the like.

In many embodiments of the system, analyte information derived by thesensor/on body electronics (for example, on body electronics assembly)is made available in a user-usable or viewable form only when queried bythe user such that the timing of data communication is selected by theuser. The on-body electronics may take periodic measurement and recordsuch data until an on-demand reading is taken by the user (e.g., thedisplay device brought in close vicinity of the on-body electronics andsensor). Upon communication, the on-body electronics may communicate therecorded data for a set time period. For example, the on-bodyelectronics may have 8 hours of memory in which it stores periodicmeasurements taken every 15 minutes. When an on-demand reading is taken,the entire 8 hours is transferred to the device. It should beappreciated that if the user does not take an on-demand reading forlonger than 8 hours, some of the data may be lost.

Accordingly, in certain embodiments once a sensor electronics assemblyis placed on the body so that at least a portion of the in vivo sensoris in contact with bodily fluid such as ISF and the sensor iselectrically coupled to the electronics unit, sensor derived analyteinformation may be communicated from the on body electronics to adisplay device on-demand by powering on the display device, andexecuting a software algorithm stored in and accessed from a memory ofthe display device, to generate one or more request commands, controlsignal or data packet to send to the on body electronics. The softwarealgorithm executed under, for example, the control of the microprocessoror application specific integrated circuit (ASIC) of the display devicemay include routines to detect the position of the on body electronicsrelative to the display device to initiate the transmission of thegenerated request command, control signal and/or data packet.

Display devices may also include programming stored in memory forexecution by one or more microprocessors and/or ASICs to generate andtransmit the one or more request command, control signal or data packetto send to the on body electronics in response to a user activation ofan input mechanism on the display device such as depressing a button onthe display device, triggering a soft button associated with the datacommunication function, and so on. The input mechanism may bealternatively or additionally provided on or in the on body electronicswhich may be configured for user activation. In certain embodiments,voice commands or audible signals may be used to prompt or instruct themicroprocessor or ASIC to execute the software routine(s) stored in thememory to generate and transmit the one or more request command, controlsignal or data packet to the on body device. In the embodiments that arevoice activated or responsive to voice commands or audible signals, onbody electronics and/or display device includes a microphone, a speaker,and processing routines stored in the respective memories of the on bodyelectronics and/or the display device to process the voice commandsand/or audible signals. In certain embodiments, positioning the on bodydevice and the display device within a predetermined distance (e.g.,close proximity) relative to each other initiates one or more softwareroutines stored in the memory of the display device to generate andtransmit a request command, control signal or data packet.

Different types and/or forms and/or amounts of information may be sentfor each on demand reading, including but not limited to one or more ofcurrent analyte level information (i.e., real time or the most recentlyobtained analyte level information temporally corresponding to the timethe reading is initiated), rate of change of an analyte over apredetermined time period, rate of the rate of change of an analyte(acceleration in the rate of change), historical analyte informationcorresponding to analyte information obtained prior to a given readingand stored in memory of the assembly. Some or all of real time,historical, rate of change, rate of rate of change (such as accelerationor deceleration) information may be sent to a display device for a givenreading. In certain embodiments, the type and/or form and/or amount ofinformation sent to a display device may be preprogrammed and/orunchangeable (e.g., preset at manufacturing), or may not bepreprogrammed and/or unchangeable so that it may be selectable and/orchangeable in the field one or more times (e.g., by activating a switchof the system, etc). Accordingly, in certain embodiments, for each ondemand reading, a display device will output a current (real time)sensor-derived analyte value (e.g., in numerical format), a current rateof analyte change (e.g., in the form of an analyte rate indicator suchas a arrow pointing in a direction to indicate the current rate), andanalyte trend history data based on sensor readings acquired by andstored in memory of on body electronics (e.g., in the form of agraphical trace). Additionally, the on skin or sensor temperaturereading or measurement associated with each on demand reading may becommunicated from the on body electronics to the display device. Thetemperature reading or measurement, however, may not be output ordisplayed on the display device, but rather, used in conjunction with asoftware routine executed by the display device to correct or compensatethe analyte measurement output to the user on the display device.

As described, embodiments include in vivo analyte sensors and on bodyelectronics that together provide body wearable sensor electronicsassemblies (also referred to herein as a “patch”). In certainembodiments, in vivo analyte sensors are fully integrated with on bodyelectronics (fixedly connected during manufacture), while in otherembodiments they are separate but connectable post manufacture (e.g.,before, during or after sensor insertion into a body). On bodyelectronics may include an in vivo glucose sensor, electronics, battery,and antenna encased (except for the sensor portion that is for in vivopositioning) in a waterproof housing that includes or is attachable toan adhesive pad.

Embodiments include sensor insertion devices, which also may be referredto herein as sensor delivery units, or the like. Insertion devices mayretain on body electronics assemblies completely in an interiorcompartment, i.e., an insertion device may be “pre-loaded” with on bodyelectronics assemblies during the manufacturing process (e.g., on bodyelectronics may be packaged in a sterile interior compartment of aninsertion device). In such embodiments, insertion devices may formsensor assembly packages (including sterile packages) for pre-use or newon body electronics assemblies, and insertion devices configured toapply on body electronics assemblies to recipient bodies.

Embodiments include portable handheld display devices, as separatedevices and spaced apart from an on body electronics assembly, thatcollects information from the assemblies and provide sensor derivedanalyte readings to users. Such devices may also be referred to asmeters, readers, monitors, receivers, human interface devices,companions, or the like. Certain embodiments may include an integratedin vitro analyte meter. In certain embodiments, display devices includeone or more wired or wireless communications ports such as USB, serial,parallel, or the like, configured to establish communication between adisplay device and another unit (e.g., on body electronics, power unitto recharge a battery, a PC, etc.).

Compatible informatics software in certain embodiments include, forexample, but not limited to stand alone or network connection enableddata management software program, resident or running on a displaydevice, personal computer, a server terminal, for example, to performdata analysis, charting, data storage, data archiving and datacommunication as well as data synchronization. Informatics software incertain embodiments may also include software for executing fieldupgradable functions to upgrade firmware of a display device and/or onbody electronics unit to upgrade the resident software on the displaydevice and/or the on body electronics unit, e.g., with versions offirmware that include additional features and/or include software bugsor errors fixed, etc.

Embodiments may include a haptic feedback feature such as a vibrationmotor or the like, configured so that corresponding notifications (e.g.,a successful on-demand reading received at a display device), may bedelivered in the form of haptic feedback.

Embodiments include programming embedded on a computer readable medium,i.e., computer-based application software (may also be referred toherein as informatics software or programming or the like) thatprocesses analyte information obtained from the system and/or userself-reported data. Application software may be installed on a hostcomputer such as a mobile telephone, PC, an Internet-enabled humaninterface device such as an Internet-enabled phone, personal digitalassistant, or the like, by a display device or an on body electronicsunit. Informatics programming may transform data acquired and stored ona display device or on body unit for use by a user.

Embodiments of the subject disclosure are described primarily withrespect to glucose monitoring devices and systems, and methods ofglucose monitoring, for convenience only and such description is in noway intended to limit the scope of the disclosure. It is to beunderstood that the analyte monitoring system may be configured tomonitor a variety of analytes at the same time or at different times.

For example, analytes that may be monitored include, but are not limitedto, acetyl choline, amylase, bilirubin, cholesterol, chorionicgonadotropin, creatine kinase (e.g., CK-MB), creatine, DNA,fructosamine, glucose, glutamine, growth hormones, hormones, ketones,lactate, oxygen, peroxide, prostate-specific antigen, prothrombin, RNA,thyroid stimulating hormone, and troponin. The concentration of drugs,such as, for example, antibiotics (e.g., gentamicin, vancomycin, and thelike), digitoxin, digoxin, drugs of abuse, theophylline, and warfarin,may also be monitored. In those embodiments that monitor more than oneanalyte, the analytes may be monitored at the same or different times,with a single sensor or with a plurality of sensors which may use thesame on body electronics (e.g., simultaneously) or with different onbody electronics.

As described in detail below, embodiments include devices, systems, kitsand/or methods to monitor one or more physiological parameters such as,for example, but not limited to, analyte levels, temperature levels,heart rate, user activity level, over a predetermined monitoring timeperiod. Also provided are methods of manufacturing. Predeterminedmonitoring time periods may be less than about 1 hour, or may includeabout 1 hour or more, e.g., about a few hours or more, e.g., about a fewdays of more, e.g., about 3 or more days, e.g., about 5 days or more,e.g., about 7 days or more, e.g., about 10 days or more, e.g., about 14days or more, e.g., about several weeks, e.g., about 1 month or more. Incertain embodiments, after the expiration of the predeterminedmonitoring time period, one or more features of the system may beautomatically deactivated or disabled at the on body electronicsassembly and/or display device.

For example, a predetermined monitoring time period may begin withpositioning the sensor in vivo and in contact with a body fluid such asISF, and/or with the initiation (or powering on to full operationalmode) of the on body electronics. Initialization of on body electronicsmay be implemented with a command generated and transmitted by a displaydevice in response to the activation of a switch and/or by placing thedisplay device within a predetermined distance (e.g., close proximity)to the on body electronics, or by user manual activation of a switch onthe on body electronics unit, e.g., depressing a button, or suchactivation may be caused by the insertion device, e.g., as described inU.S. patent application Ser. No. 12/698,129, filed on Feb. 1, 2010, andU.S. Provisional Application Nos. 61/238,646, 61/246,825, 61/247,516,61/249,535, 61/317,243, 61/345,562, and 61/361,374, the disclosures ofeach of which are incorporated herein by reference for all purposes.

When initialized in response to a received command from a displaydevice, the on body electronics retrieves and executes from its memorysoftware routine to fully power on the components of the on bodyelectronics, effectively placing the on body electronics in fulloperational mode in response to receiving the activation command fromthe display device. For example, prior to the receipt of the commandfrom the display device, a portion of the components in the on bodyelectronics may be powered by its internal power supply such as abattery while another portion of the components in the on bodyelectronics may be in powered down or low power including no power,inactive mode, or all components may be in an inactive mode, powereddown mode. Upon receipt of the command, the remaining portion (or all)of the components of the on body electronics is switched to active,fully operational mode.

Forexample, remote terminal 1170 may be located at a location other thanthe location of display device 1120. Remote terminal 1170 and displaydevice 1120 could be in different rooms or different buildings. Remoteterminal 1170 and display device 1120 could be at least about one mileapart, e.g., at least about 110 miles apart, e.g., at least about 1100miles apart. For example, remote terminal 1170 could be in the same cityas display device 1120, remote terminal 1170 could be in a differentcity than display device 1120, remote terminal 1170 could be in the samestate as display device 1120, remote terminal 1170 could be in adifferent state than display device 1120, remote terminal 1170 could bein the same country as display device 1120, or remote terminal 1170could be in a different country than display device 1120, for example.In certain embodiments, a separate, optional datacommunication/processing device such as data processing module 1160 maybe provided in analyte monitoring system 1100.

In certain embodiments, control logic or microprocessors of on bodyelectronics 1110 include software programs to determine future oranticipated analyte levels based on information obtained from analytesensor 1101, e.g., the current analyte level, the rate of change of theanalyte level, the acceleration of the analyte level change, and/oranalyte trend information determined based on stored monitored analytedata providing a historical trend or direction of analyte levelfluctuation as function time during monitored time period. Predictivealarm parameters may be programmed or programmable in display device1120, or the on body electronics 1110, or both, and output to the userin advance of anticipating the user's analyte level reaching the futurelevel. This provides the user an opportunity to take timely correctiveaction.

Information, such as variation or fluctuation of the monitored analytelevel as a function of time over the monitored time period providinganalyte trend information, for example, may be determined by one or morecontrol logic or microprocessors of display device 1120, data processingmodule 160, and/or remote terminal 1170, and/or on body electronics1110. Such information may be displayed as, for example, a graph (suchas a line graph) to indicate to the user the current and/or historicaland/or and predicted future analyte levels as measured and predicted bythe analyte monitoring system 1100. Such information may also bedisplayed as directional arrows (for example, see trend or directionalarrow display 1131) or other icon(s), e.g., the position of which on thescreen relative to a reference point indicated whether the analyte levelis increasing or decreasing as well as the acceleration or decelerationof the increase or decrease in analyte level. This information may beutilized by the user to determine any necessary corrective actions toensure the analyte level remains within an acceptable and/or clinicallysafe range. Other visual indicators, including colors, flashing, fading,etc., as well as audio indicators including a change in pitch, volume,or tone of an audio output and/or vibratory or other tactile indicatorsmay also be incorporated into the display of trend data as means ofnotifying the user of the current level and/or direction and/or rate ofchange of the monitored analyte level. For example, based on adetermined rate of glucose change, programmed clinically significantglucose threshold levels (e.g., hyperglycemic and/or hypoglycemiclevels), and current analyte level derived by an in vivo analyte sensor,the system 1100 may include an algorithm stored on computer readablemedium to determine the time it will take to reach a clinicallysignificant level and will output notification in advance of reachingthe clinically significant level, e.g., 30 minutes before a clinicallysignificant level is anticipated, and/or 20 minutes, and/or 10 minutes,and/or 5 minutes, and/or 3 minutes, and/or 1 minute, and so on, withoutputs increasing in intensity or the like.

In some aspects, the display device (also referred to herein as “analytemonitoring device” or simply “device”) is configured to receive a signalfrom a remote sensor using radio-frequency identification (RFID)technology.

This configuration may be used to provide glucose on demandcapabilities, for example, in which case when a measurement reading isdesired, the analyte monitoring device is brought within close vicinityof the implantable sensor. It should be appreciated that in otherembodiments the wireless communication unit may communicate with thesensor using a different wireless communication technology than RFID.When within range, the device may be configured to verify that thesensor is the appropriate sensor that it has been configured to operatewith. If not, the device ignores the sensor and does not initiateoperation with the sensor. If so, the device initiates operation withthe sensor.

The analyte monitoring device may perform a variety of functions,including for example: modifying the signals from the sensor usingcalibration data and/or measurements from a temperature probe (notshown); determining a level of an analyte in the interstitial fluid;determining a level of an analyte in the bloodstream based on the sensormeasurements in the interstitial fluid; determining if the level, rateof change, and/or acceleration in the rate of change of the analyteexceeds or meets one or more threshold values; activating an alarmsystem if a threshold value is met or exceeded; evaluating trends in thelevel of an analyte based on a series of sensor signals; therapymanagement (e.g., determine a dose of a medication, etc.); and reducenoise or error contributions (e.g., through signal averaging orcomparing readings from multiple electrodes); etc. The analytemonitoring device may be simple and perform only one or a small numberof these functions or the analyte monitoring device may perform all ormost of these functions.

Software for the Remote Device

In some aspects, the analyte monitoring device may be communicativelycoupled to a remote data processing device for management purposes.Remote device may include, for example, a personal computer, laptop,PDA, cellular phone, smartphone, set-top box, etc. The remote device mayinclude, for example, a control unit including any variety of processor,microprocessor, microcontroller, etc. The remote device may also includea memory unit comprising non-volatile memory and volatile memory.

The term “remote device” is used herein to represent any device that isexternal to the analyte monitoring device. The remote device may requiresoftware to fully communicate with the analyte monitoring device, managedata from the analyte monitoring device, modify settings on the analytemonitoring device, or otherwise operate with analyte monitoring device.This auto-assisting user interface software is referred to herein as“remote device software” or “RD software” or “data management software”to distinguish it from the user interface software running on theanalyte monitoring device. The RD software may be obtained from one ormore methods such as downloading from the web, CD-ROM, memory stick,etc. The RD software is generally discussed here and additional detailsregarding various flows and screens are provided later.

In some embodiments, the analyte monitoring device includes the RDsoftware programs and/or applications to be run on the remote device. Insome instances, the RD software may be configured to automaticallylaunch when the analyte monitoring device is coupled to the computer.For example, the analyte monitoring device may include an installerprogram that is stored in non-volatile memory and executed when theanalyte monitoring device is coupled to the remote device. The installerprogram may be executed when the user couples the analyte monitoringdevice to the remote device. The installer program may then initiate thelaunch of the RD software on the remote device.

In some embodiments, the RD software is not stored in non-volatilememory on the remote device. The RD software is stored on the analytemonitoring device and used to launch the RD software on the remotedevice is coupled to the analyte monitoring device.

In some embodiments, the RD software may be downloaded and stored innon-volatile memory on the remote device. For example, the RD softwaremay be downloaded via a network connection (e.g., via an internetconnection), by storage device (e.g., CD-ROM, memory stick, etc.),and/or downloaded from the analyte monitoring device. In some instances,the RD software is capable of being run even when the device is notcoupled to the computer.

It should be understood that the RD software may be compatible withvarious hardware systems (e.g., PC, MAC) and various operating systems(e.g., Windows, MAC OS, Linux).

The analyte monitoring device may be communicatively coupled to theremote device via wired technologies. Example wired technologies mayinclude, but are not limited to, the following technologies, or familyof technologies: USB, FireWire, SPI, SDIO, RS-232 port, etc.

The analyte monitoring device may include, for example, a communicationconnector unit to permit wired communication and coupling to the remotedevice. The communication connector unit provides the capability tocommunicate with a remote device having an appropriate interface tooperatively couple with the communication connector. In someembodiments, the communication connector is configured to communicatewith a smartphone such as an iPhone or Blackberry.

The communication connector unit may be any variety of connectioninterfaces—e.g., male or female connection interfaces. Using USB as anexample, the communication connector may be any of the variety of USBplugs or USB receptacles/ports. As USB receptacles are typically locatedon computer and other devices, a corresponding USB plug used as acommunication connector unit will enable the analyte monitoring deviceto be plugged directly into the USB receptacle, avoiding the use ofcables. In other instances, the appropriate USB receptacle may be usedon the analyte monitoring device to enable communication using a USBcable (similar to many other devices such as digital cameras, cellularphones, smartphones, etc.).

It should be appreciated that the in some embodiments the analytemonitoring device may be communicably coupled to the remote device viawireless technology. In such instances, the analyte monitoring devicemay include corresponding transmitters, receivers, and/or transceivers.The analyte monitoring device may be configured to wirelesslycommunicate using a technology including, but not limited to, radiofrequency (RF) communication, Zigbee® communication protocols, WiFi,infrared, wireless Universal Serial Bus (USB), Ultra Wide Band (UWB),Bluetooth® communication protocols, and cellular communication, such ascode division multiple access (CDMA) or Global System for Mobilecommunications (GSM), etc.

The functionality of the RD software launched on the remote device mayinclude a variety of functions relating to, for example, dataacquisition; data management; management of features, settings,configurations, etc., of the analyte monitoring device; generation,saving, transmitting, and/or printing of reports, management of updates(e.g., field updates to device firmware and RD software); access totraining content, web-based content, web-based marketing; etc.

The RD software may be launched on a remote device and used by the user(e.g., the patient) and/or a health care provider (HCP) (e.g.,physician, hospital staff, etc.). For example, the HCP and/or patientmay use the RD software on a remote device to analyze the patient data,view and print reports, view and change device settings, update devicefirmware and application software, etc.

In some instances, the RD software may initiate a comparison between thetime date on the analyte monitoring device and that on the remote deviceand/or remote time server accessed via an internet connection from theremote device. The RD software may account for discrepancies and takeaction accordingly. For example, thresholds may be set (e.g., 5 minutedifference) and if the threshold is reached, the analyte monitoringdevice prompts the user with a warning, question, indicator, etc., toacknowledge the discrepancy and/or remedy the discrepancy (e.g., adjustthe time on one of the devices). In some instances, a similar comparisonmay be performed by the RD software to account for other discrepanciesbetween the analyte monitoring device and remote device—e.g.,discrepancies between data logs, data values, stored files, deviceand/or user interface configurations and settings, etc. The appropriateaction can then be taken or requested.

Various defaults and customized configurations and settings may beestablished for generating, printing, saving, exporting, etc., reports.For example, the various formats for the report may be established(e.g., layout, style, themes, color, etc.); various file types to savethe report as (e.g., PDF, Word document, Excel spreadsheet, etc. In someinstances, for example, the RD software may provide the user with theability to export tab-delimited text files or XML exports of the meterdata (e.g., including blood glucose, ketones, carbs, insulin, and eventtags, etc.). In some instances, the RD software may enable the user tosave, print, and/or export preferences, including favorite reports,target blood glucose ranges, auto save, auto print, color/black andwhite printing, device/software update settings for multiple devices,etc.

In some aspects, the RD software is used to control the configuration ofthe device and data from the device. This control may be utilized by theuser and/or HCP. In some instances, the RD software shall provide accessto one or more informative documents, trainings, tutorials, etc. Forexample, the RD software application may provide links or tomanufacturer sponsored websites intended for any variety of purposessuch as marketing and training content.

In some aspects, the RD software may include an update managementfunction to help facilitate the detection, download, and installation ofupdates (e.g., firmware, informatics application updates, etc.) for theanalyte meter device and/or the RD software.

Example Devices & Systems

FIG. 2 illustrates a block diagram of a system including an analytemonitoring device and remote data processing device, according to someembodiments. System 1500 is shown to comprising analyte monitoringdevice 1501 communicably coupled to remote device 1505. In someinstances, as shown, remote device 1505 may have network access to anetwork 1510 in which a second remote device 1515 is shown coupled to.It should be understood that network 1510 may include one or morenetworks, including LANs, WANs, and/or the internet.

Analyte monitoring device 1501 is shown removably coupled to remotedevice 1505 via communication connector unit 1422. Communicationconnector unit, for example, includes a USB plug which couples with aUSB receptacle 1507 in remote device 1505. Remote device 1505 mayinclude peripheral devices, such as printer, keyboard, monitor, CDdrive, etc. Remote device 1505 may also include, as shown, a networkinterface 1530 which connects it to network 510. Remote device 1515 isalso connected to network 1510 and may communicate with remote device1505 via network 1510.

The following paragraphs describe system 1500 during operation,according to some embodiments. In some instances, the analyte monitoringdevice described is a glucose monitoring device which measures theglucose concentration level of a blood sample. It should be understoodthat the description applies equally to other analytes and to otherforms of samples.

In use, analyte monitoring device 1501 receives a test strip 1525 formeasuring an analyte level of a sample applied to test strip 1525. Teststrip 1525 is received at strip port unit 1520. Analyte monitoringdevice 1501 performs a measurement computation on the sample and theuser can view the measurement reading on, for example, a touchscreendisplay (not shown). The user may also be presented with a menu on thetouchscreen display to view and select—e.g., menus for storing data,downloading data, performing bolus calculations based on themeasurement, etc.

The user may couple the analyte monitoring device 1501 to remote device505 (e.g., a personal computer) via a communication connector unit. Forexample, the user may decide to store the measurement data and thenchoose to download stored test data (including stored measurementreadings) to a remote device 1505.

Analyte monitoring device 1501 may then be coupled to remote device 1505via communication connector unit 1422. Communication connector unit 1422may, for example, include a USB plug which couples to a USB receptacle1507 on remote device 1505.

In some instances, the analyte monitoring device 1501 may be powered bythe remote device 1505 when coupled via the communication connector unit1422. In such case, the user would couple the analyte monitoring device1501 to the remote device 1505 and then insert test strip 1525 into thestrip port 1520 to take a measurement reading. In some instances, theanalyte monitoring device includes its own power source, such as buttonor AAA-size batteries, for example, and is not powered by the remotedevice 1505.

In some instances, the analyte monitoring device may be “locked” orprevented from performing a test while coupled to the remote device1505. For example, medical device regulations such as high voltageisolation testing may be required if the analyte monitoring device isconfigured to perform tests while coupled to a remote device. Thus,“locking” or preventing the analyte monitoring device from performing atest while coupled to the remote device allows the analyte monitoringdevice to not be subjected to the additional testing, if so desired.

In some aspects, the analyte monitoring device 1501 may initiate a userinterface application (e.g., RD software) to execute on the analytemonitoring device, and/or the remote device 1505 when coupled to theremote device 1505. The user interface application may be stored in amemory unit on the analyte monitoring device 1501, for example. In someaspects, the user is not required to have previously loaded software onthe remote device 1505 to operate with the analyte monitoring device1501. In some aspects, the analyte monitoring device may be configuredto initiate the user interface application automatically upon couplingto the remote device. It should be understood that the user interfaceapplication may be configured to be compatible with various hardwaresystems (e.g., PC, MAC) and various operating systems (e.g., Windows,MAC OS, Linux).

The user interface application may include, for example, diabetesmanagement related applications. The user interface application mayprovide a variety of menus, selections, charts, alarms, reminders,visual indicators, etc. For example, the user may be presented withmenus and options, such as whether to take a measurement reading, toview stored measurement readings, to store data, to download data, toperform bolus calculation based on the measurement, etc.

The user interface program may, for example, allow the user to performthe following steps: (1) generate a replica of the test data stored onthe analyte monitoring device 1501, on the remote device 1505; and (2)synchronize test data from the analyte monitoring device 1501 to thedatabase on the remote device 1505. Meter settings and/or usersettings/preferences from the analyte monitoring device may also beincluded in the test data and synchronized with the remote device. Dateand time for the remote device 1505 and analyte monitoring device 1501may also be synched.

To read test data from the analyte monitoring device 1501 and write itto the remote device 1505, it is recognized herein that data in theremote device may be organized into tables, which may be organized intorecords, which may be broken down into predefined fields. Similarly, atsome level data will be organized into records with a consistent fieldstructure on the analyte monitoring device 1501. The user interfaceapplication may read test data from the analyte monitoring device andwrite it out to tables on the remote device 1505. The user interfaceapplication may also read data from table in the remote device 1505 andwrite them out to the analyte monitoring device 1501. Various types ofdata conversion may be used. For example, data residing in fields in theanalyte monitoring device may be converted from the format it exists inthe analyte monitoring device to a format compatible with the remotedevice, and vice versa. The logical structure of the records in the twosystems may be different.

Remote device 1505 may include peripheral devices, such as printer,keyboard, monitor, CD drive, etc. Remote device 1505 includes a networkinterface which connects it to network 1510 (e.g., the internet). Theuser interface application may provide the user with the option to viewtest data on the monitor, to store test data on storage media (e.g.,CD-ROM, memory card, etc.), further analyze and/or manipulate test data,transmit data to another device), and/or print out test data such ascharts, reports, etc., on the printer.

As shown, remote device 1505 may also include a network interface 1530(e.g., network interface card (NIC), modem, router, RF front end, etc.)used to connect the remote device 1505 to network 1510. For example, insome aspects, analyte monitoring device 1501 may couple via a USBconnection to the remote device which may be a personal computer orlaptop connected to the internet using a wireless modem and/or router.In some aspects, analyte monitoring device 1501 may couple via a microUSB connection to a remote device 1505 which is a smartphone having anRF front end to access a mobile network. The user interface applicationmay provide a user interface for using the network connection of theremote device 1505—e.g., to forward test data to a physician, hospital,health provider, and/or other third party located at a second remotedevice 1515 on network 1510. Appropriate action may then be taken by thereceiving party at the second remote device 1515.

FIG. 4 illustrates a method 100 of powering on an analyte monitoringdevice, such as a glucose monitoring device, according to oneembodiment. The analyte monitoring device may also be referred to hereinas a “reader” which takes measurement readings from the analyte sensor.From the off state, as represented by block 102, the device can bepowered on by depressing a power button—e.g., by a “short press” or a“long press”, as represented by block 104. At block 106, a test isperformed to determine if the battery is depleted. If so, the device ispowered off, as shown by block 107. In some instances, when the devicerecovers from a power loss, it can remember “sensor” status informationand resume use of the same sensor if the sensor has not expired—e.g., a14-day period, or other predetermined period, has not elapsed. If thebattery is determined to not be depleted, then the device is powered on,as shown at block 108.

At block 110, the device processor determines the presence of any errorsin the hardware functionality of the device. Upon being powered on, ifthe device processor determines a hardware failure, such as the deviceis not working properly, the device will display a hardware errormessage as shown at block 111, such as those described herein below inthe present application. If no hardware errors are detected, at block112, it is determined if this is the first time the device is to be setup. If it is the first time, then a First Start procedure is initiatedto begin the setup of the device, as shown at block 114. If it isdetermined that this is not a first time setup, then it is determined ifthe sensor has already been activated. If not activated, then the homescreen is displayed, as shown at block 118. If already activated, thenit is determined whether the sensor is expired, as shown at block 120.If the sensor is expired, it is determined if the sensor expirationmessage has been previously displayed, as shown at block 130. If so,then the home screen is displayed, as shown at block 134. If not, then asensor expiration screen is displayed, as shown at block 132. In someinstances, an audible notification may also be provided. The sensorexpiration screen may also inform the use that a new sensor must bestarted to take a glucose reading. Once confirmed by the user, forexample by pressing “ok”, the home screen is displayed on the device.

Referring back to block 120, if the sensor is not expired, then it isdetermined if the sensor is warming up, as shown by block 122. If not,then a prompt is displayed for a sensor scan. If the sensor is warmingup, then a warm-up message screen is displayed that informs the userthat the sensor is warming up, as shown at block 126. In some instances,such as shown, the warm-up message screen indicates the time remainingbefore the sensor can be used. An audible reminder may also be present,as shown. Once confirmed by the user, for example by pressing “ok”, thehome screen is displayed on the device.

When the home trigger button is pressed, the deviceprocessor checks whether the sensor is expired, e.g., after 14 days, asshown at block 143. If the sensor is expired, then a sensor expirationscreen is displayed, as shown at block 144. In some instances, anaudible notification may also be provided. The sensor expiration screenmay also inform the user that a new sensor must be started to take aglucose reading. Once confirmed by the user, for example by pressing“ok”, the home screen is displayed on the device, as shown at block 145.If the sensor is not expired, then the home screen is displayed, asshown at block 146. An alternative home screen 148 is shown that doesnot include a reminder. In some instances, a short press of the triggerbutton for the home screen is not activated when a test strip isinserted within the device a prior to receiving a result. It should beappreciated that there may be some screens in which the home triggerbutton does not lead to a display of the home screen. In someembodiments, from some screens, pressing the home trigger button doesnot navigate to the home screen. Such exceptions are described hereinbelow.

FIG. 5B illustrates a method 150 of powering an analyte monitoringdevice off, according to one embodiment. At block 152, a current screenis displayed on the device. When a screen has been displayed for apredetermined period of time—e.g., 45 seconds or some other period oftime, the screen brightness may dim to say power, as shown at block 154.If the user touches the dimmed screen the display returns to fullbrightness and the timeout timer resets. After the screen is dimmed, ifanother predetermined period of time has passed without anyactivity—e.g., 15 seconds or other time period—then the device willpower off. It should be appreciated that there may be certain screens inwhich such method does not apply.

FIG. 5C illustrates a method 160 of powering an analyte monitoringdevice off, according to one embodiment. From the home screen, shown atblock 162, the pressing (e.g., short or long) of the home triggerbutton, as shown at block 164, will trigger the display of a screenindicating the device is powering off. The user may be provided with anoption to cancel the power down process.

FIG. 6A illustrates a method 220 for performing a sensor scan or systemcheck, according to one embodiment. From the home screen at block 222,if a glucose check is initiated, it is determined if a system check isrequired, as shown at block 230. If so, then a system check isperformed, as shown at block 232. If a system check is not required,then a sensor scan prompt is displayed, as shown at block 234. The homescreen may enable other features to be initiated as well. For example, areader's summaries menu screen may be displayed when the correspondingicon is triggered at the home screen, as shown by block 224. Also, asettings screen may be displayed when the corresponding icon istriggered at the home screen, as shown by block 226.

In addition, an insulin on board screen may be displayed when thecorresponding icon is triggered at the home screen, as shown by block236. The insulin on board screen provides information related to theestimated active insulin remaining in a user's body according to insulindata previously entered. Additional details may be provided when acorresponding icon is initiated from the insulin on board screen. In oneembodiment, a timer counts down from time of dose for insulin durationas set in a calculator setup. In one embodiment, the insulin on boardscreen with active countdown appears if the insulin on board is enabledin the calculator setup and the insulin on board is calculated to bepresent. The icon shown provides a visual indication that reflects theamount of rapid-acting insulin estimated to be still in body—e.g., apercentage of the body-shaped icon filled corresponding to a percentageof the active insulin remaining in the body.

Also, a reminder screen may be displayed when the corresponding icon istriggered at the home screen, as shown by block 228. In one embodiment,when a reminder is set, the time at which the alarm will sound appearsnext to a reminders icon. If, for example, multiple reminders areactive, the time shown is the time of the reminder that will soundsoonest.

Expired/No Sensor Interface

FIG. 6B illustrates a method for activating a sensor, according to oneembodiment. In the embodiment shown, the home screen 242 indicates thatno sensor is currently paired to the analyte monitoring device isdisplayed on the device. For example, a sensor may have never beenpaired to the device, or a previously paired sensor may have expired.From home screen 242, the user may trigger the activation of a sensor bypressing or otherwise selecting a corresponding icon or other triggerelement displayed on the display of the device.

Sensor Warming Up Interface

FIG. 6C illustrates a method 246 for activating a sensor, according toone embodiment. After a user initiates the activation of a sensor, e.g.,as represented by block 250, the device may indicate if the sensor iswarming up. As illustrated, during the warm up period, the home screen248 indicates that the sensor is warming up. For example, home screen248 indicates the time remaining before the sensor is ready, as shown inscreen 248—e.g., “Ready in 60 min”.

Sensor Near Expiration Interface

FIG. 6D illustrates a method 252 for scanning a sensor if the sensor isnearing expiration, according to one embodiment. In the embodimentshown, a screen 254 indicates the time remaining before the currentlypaired sensor is expired—e.g., in 16 hours. From home screen 254, theuser may still trigger the activation of a sensor by pressing orotherwise selecting a corresponding icon or other trigger elementdisplayed on the display of the device, since the sensor is not yetexpired.

Sensor Life Display in Title Bar

FIG. 6E illustrates exemplary embodiments of a graphical user interfacedisplaying sensor life in varying increments. In the embodiment shown,sensor life is displayed in three ranges: days, hours, and minutes asshown in screens 257, 258 and 259, respectively. In certain embodiments,the sensor life is rounded up—e.g., 2 days 1 hour is displayed as 3days, 1 day 20 hours is displayed as 2 days, 1 hour 10 minutes isdisplayed as 2 hours. In embodiments, the sensor life display isindependent of a user adjustable date and time.

Sensor Activation

An exemplary embodiment of a graphical user interface which may beutilized in connection with a reader as described herein and whichfunctions activate the sensor is provided.

FIG. 7 illustrates a method 260 for activating a sensor after the deviceis powered on, according to one embodiment. At block 261, the device ispowered on. Once powered, a home screen 262 is displayed. The homescreen 262 indicates that there is no active sensor, and furtherincludes an icon or other trigger element that enables the start of anew sensor. Once icon is selected by the user, as represented by block263, a “Start New Sensor” screen 264 for starting the sensor isdisplayed. The start new sensor screen 264 enables the user to start anew sensor—e.g., by informing the user to scan the sensor to start it.Upon the start of the scan, the device waits (e.g., 15 seconds) for thescan to complete, as shown by blocks 265 and 266. If the wait periodelapses and the scan is not yet complete, the device may display ascreen informing the user that the scan has timed out 267.

Upon completion of the scan, to start a pairing of the device andsensor, the device may check the sensor for errors, including anintegrity check of the scan 268, a health check of the sensor 270 and anexpiration of the sensor check 272. If the device determines that thescan failed, the device may display a screen indicating that a scanerror occurred, as shown at block 269. If the device determines that thesensor in not functioning properly, the device may display a screenindicating to replace the sensor with a new sensor 271. If the scansucceeds and the sensor is found to be functioning, the device may checkthe expiration information of the sensor, and if expired, e.g., a usertried to continue use of an expired sensor, the device may display asensor expired screen 273. From any of the scan error, replace sensor,and sensor expired screens, selecting “ok” may navigate the device backto the home screen 262 to start a new sensor again.

Referring to block 275, if the sensor has already been activated byanother device, then a screen 276 indicating that the sensor is alreadypaired with another device is displayed. Upon user confirmation, thehome screen is displayed, as shown at block 277. In certain embodiments,when a sensor is already paired with another reader device, use of thatsensor with the new reader device is not allowed.

In some instances, the device may include a masked mode that enables theuser to take readings of a paired sensor, but does not display theresulting readings to the user, or otherwise limits the resulting datato the user. After a non-expired sensor has been successfully scanned,the device may display a masked mode screen to indicate a masked mode iscurrently enabled. For example, masked mode screen 279 indicates thatthe device will operate in the masked mode, unless otherwise changed. Insome instances, the initial configuration may be set up by the doctor orother health care profession for the patient. In certain configurations,the masked mode may only be deactivated by a health care professional.If the device is not operating in a masked mode, or after the userconfirms the masked mode, then a warm up message screen 280 is displayedthat indicates that the sensor is warming up. The remaining time forwarm up may also be displayed. If the user confirms the message, forexample by selecting the “ok” icon, then the device may navigate back tothe home screen 281 and the home screen is displayed and indicates thesensor is warming up—e.g., by showing the remaining time until thesensor is ready. If the user attempts to perform a sensor scan as shownby block 282—e.g., by selecting the check glucose icon, then the warm upmessage screen 281 is displayed again. In some instances, the homescreen may be displayed after a predetermined time showing the warm upmessage or the device will automatically navigate to the home screen 283after the sensor is ready. In certain embodiments, the device will notdisplay a message screen showing “0 minutes” remaining.

Sensor Scan and Results

Exemplary embodiment of a graphical user interfaces which may beutilized in connection with a reader as described herein and whichfunction to scan and to provide results are provided.

Sensor Scan Interface

FIG. 8 illustrates a method 300 for scanning a sensor with an analytemonitoring device, according to one embodiment. At block 301, the deviceis powered on. A scan prompt screen 302 is displayed and indicates tothe user to scan the sensor to check an analyte level (e.g., glucoselevel).

In the embodiment shown, an icon or trigger element is provided onscreen 302 for going to the home screen 303. If selected by the user,the home screen 303 is displayed. From the home screen 303, the user mayinitiate a sensor scan thereafter and return to the scan prompt screen302.

Upon the start of the scan, the device waits (e.g., 15 seconds) for thescan to complete, as shown by blocks 304 and 305. If the wait periodelapses and the scan is not yet complete, the device may display ascreen informing the user that the scan has timed out 306. Uponcompletion of the scan, the device may perform an integrity check of thescan 307. If the device determines that the scan failed, the device maydisplay a screen indicating that a scan error occurred, as shown atblock 308 and instruct the user to scan the sensor again.

If the sensor is a new inactive sensor, as shown at block 309, then anew sensor detected screen 310 is shown and indicates that the sensor isa new sensor. Screen 310 provides the user with an option to start thenew sensor or not. If the user elects to start the new sensor, then thedevice initiates the sensor activation process, as shown by block 312.If the user elects to not start the new sensor, then the device displaysthe home screen, as shown by block 311.

If the device determines that the current sensor is inactive, as shownat block 313, then a check sensor screen 314 is displayed and indicatesthat there may be a problem with the sensor. The check sensor screen314, in some embodiments, may suggest to the user to check if the sensoris loose or has fallen out. If the sensor is loose, the loose sensorshould be removed and a new sensor shall be paired. If the sensor iscorrectly applied, then the sensor is scanned again.

Referring to block 315, if the sensor has already been activated byanother device, then a screen 316 indicating that the sensor is alreadypaired with another device is displayed. Upon user confirmation, thehome screen is displayed. In certain embodiments, when a sensor isalready paired with another reader device, use of that sensor with thenew reader device is not allowed.

The device may check the expiration information of the sensor as shownat block 317, and if expired, e.g., a user tried to reuse an expiredsensor, the device may display a sensor expired screen 318. From any ofthe scan error, replace sensor, and sensor expired screens, selecting“ok” may navigate the device back to the home screen to start a newsensor again.

If the device determines that the sensor in not functioning properly,the device may display a screen indicating to replace the sensor with anew sensor 271. If the scan succeeds and the sensor is found to befunctioning, the device determines whether the sensor is to expirewithin a predetermined amount of time, such as within the next 3 days,as shown at block 321. It should be appreciated that the amount of timemay vary in other embodiments, and in one embodiment check to see if thesensor is expired. It should also be appreciated that the predeterminedamount of time may be preprogrammed in manufacturing, and/or set withinthe settings, etc. If at block 321, it is determined that the sensor isexpiring within the predetermined amount of time, then a sensor nearexpiration screen 322 is displayed to indicate the sensor is close toexpiring. The remaining time until the sensor expires may be displayed,for example. In certain embodiments, the remaining time message isdisplayed after the first scan of the day for the last three days of thesensor life and the screen is shown after every scan for the last 8hours before sensor expiration. The screen showing the remaining timeuntil sensor expiration may be displayed as days remaining, when thelength of time is 2 days or more, hours remaining, when the length oftime is between 2 hours and 1 day, and minutes remaining, when thelength of time is less than an hour, wherein the time remaining isrounded up as described above in conjunction with FIG. 6E. If the timeremaining screen is still active when the time remaining reaches zero,the device may automatically navigate to the Sensor Results with noactive sensor screen, as described herein below.

If at block 321, it is determined that the sensor is not expiring withinthe predetermined amount of time, then it is determined whether thesensor battery is low, as represented at block 325. If the battery islow, then at block 326, the device indicates that the battery islow—e.g., via a low battery screen, or a low battery icon, etc. In someinstances, a reading is not taken, and no results are shown for thescan.

If the battery is not low, then at block 327, it is determined if theskin temperature is too hot or cold—e.g., using a “safe” range oftemperatures. The sensor may provide the temperature data to the device.If the temperature is determined to be too hot or cold, then the devicedisplays the resulting reading and indicates that the sensor temperaturewas too hot or too cold, respectively, as shown at block 328. If theskin temperature is not too hot or cold, then it is determined whetherthe quality of the data is acceptable, as shown at block 329. If thedata quality checks fail, the device may display a sensor error screen330, informing the user that the glucose reading is unavailable. Incertain embodiments, the device may suggest to the user to rescan aftera predetermined waiting period, such as 10 minutes. Upon selection bythe user of the “ok” confirmation element, the device may navigate backto the home screen 331.

As shown at block 332, it is determined whether the resulting reading isout of range. If the sensor is out of range, then it is determined if ahigh or low glucose condition has occurred. For example, a target rangeor acceptable range may be preset by the manufacturer or customizable bythe user. If a high or low condition is present, then the user is takento the Sensor Results screen, as shown at block 333, and the high or lowcondition may be indicated on the Sensor Results screen (e.g., via amessage, icon, etc.) along with the sensor results.

Referring back to block 332, if it is determined that the sensor is notout of range, then it is determined if the glucose level was a high orlow glucose level 334. For example, a high or low glucose level may bepreset by the manufacturer or customizable by the user. If a high or lowglucose level is present, then the user is taken to the Sensor Resultsscreen, as shown at block 335, and the sensor results may be displayed.If a high or low condition is not present, then it is determined whethera high or low condition is projected, as shown at block 336. A high orlow condition may be projected, for example, by trends in themeasurement readings. If a high or low condition is projected, then theuser is taken to the Sensor Results screen and the projected high or lowcondition is indicated on the Sensor Results screen along with thesensor results, as shown at block 337.

In some instances, the device is programmed such that the skintemperature test takes priority over other test conditions (e.g.,out-of-range test, high/low glucose test, projected high/low glucosetest, etc.) that may occur simultaneously.

Consecutive Scans Interface

An exemplary embodiment of a graphical user interface which may beutilized in connection with a reader as described herein and whichfunctions to provide navigation when consecutive scans are present isprovided.

Two Scans within Predetermined Period of Time

In some aspects, the analyte reader device is programmed to performspecific navigations when the device is scanned multiple times within apredetermined period of time.

FIG. 9A illustrates a method 350 for performing two scans within apredetermined period of time with the analyte reader, according to oneembodiment. After the first scan is performed, a Sensor Results screenis displayed, as shown at block 352. If the power is turned off or theSensor Results screen is left before a predetermined period of time(e.g., 3 minutes in the example embodiment shown), the results from thefirst scan are saved, as represented by block 354. If the device ispowered back on, or another scan is attempted, within the predeterminedperiod of time, the device will prevent the user from performing a newscan and display a No New Scan screen indicating that a new sensorreading is not available at this time, as shown by blocks 356 and 358.The No New Scan screen may also indicate the time remaining untilanother scan, as well as, enable the user to view the last SensorResults screen if desired, as represented by Sensor Results screen 362.

Device Timeout at the Suggest Dose Screen from BG Result

In some aspects, the analyte reader device is programmed to return to asaved suggested dose screen if the reader is powered off or leaves a“Calculator/Suggested Dose” screen when a dose has been calculated butnot logged, and the device is powered back on or another scan isattempted within a predetermined period of time.

FIG. 9B illustrates a method 364 of logging a dose calculation,according to one embodiment. After a glucose reading is taken, a“Calculator/Suggested Dose” (CALC SGTD) screen 366 may be displayed tocalculate and log a suggested dose of insulin. From screen 366, the usercan adjust the suggested does if desired and log the dose. However, ifwithin a predetermined period of time (e.g., 3 minutes in the embodimentshown), the device is powered off, or screen 366 is left, after asuggested dose has been calculated but not logged, then the suggesteddose data is saved, as shown at block 368. If the device is powered backon, or another glucose scan is attempted, within the predeterminedperiod of time, as shown by block 370, then the user is returned to theCALC SGTD screen 372 having the saved suggested dose data. From here,the user may continue with the dose calculation and log the calculateddose. If a dose is logged at this point, the dose is stored within theLogbook along with the test results. In one embodiment, the dose islogged as having been taken at the time the test was taken rather thanat the time the dose was actually logged. The insulin in body countdown,however, starts from the time at which the does is actually logged.

Suggested Dose from BG Result Logged

In some aspects of the present disclosure, after a first scan andcalculated insulin dose logged, the device is programmed to prevent asecond scan within a predetermined period of time from a first scan. Theuser will not be able to perform the second scan, but will be able toview the Logbook.

FIG. 9C illustrates a method 374 for enabling two consecutive scans,according to one embodiment. At block 376, the reader is powered off, orthe Sensor Results screen is left, within a predetermined period of timeafter a first scan was taken (e.g., 3 minutes in the embodiment shown).If the device is powered back on, or another scan is attempted, withinthe predetermined period of time from the first scan, as shown at block378, then the second scan is prevented from occurring until thepredetermined period of time has lapsed. A No New Scan screen 380 isdisplayed indicating that another scan is not currently permitted. Insome instances, as shown, screen 380 provides the time remaining untilanother scan can be taken. In the embodiment shown, user confirmationform screen 380 takes the user to the Home screen as shown at block 382.Screen 380 may also provide a selection to allow the user to view thelast reading in the Logbook, as shown at block 384.

Sensor Results Interface

In some aspects of the present disclosure, a graphical user interface isprovided that may be utilized in connection with a reader as describedherein and which functions generally to provide sensor results.

Results

FIG. 10A illustrates an example Sensor Results screen 388, according toone embodiment. Screen 388 may be provided, for example, after a scanhas been successfully performed. The example sensor results screen 388is shown to include a sensor reading 389 a, a graph 389 b of glucosereadings taken, and various reader/sensor related information, such as atrending arrow, current time, battery life, sensor expiration, etc. Incertain embodiments, time may be displayed in 24-hours format or 12-hour(am/pm) format. In certain embodiments, numerical glucose results may bedisplayed in selectable units, e.g. mg/dL as shown in FIG. 10A, ormmol/L as shown in FIG. 10L, or others. A trigger element 389 c fornavigating to the Notes interface is also provided to take the user tothe Notes screen as shown by block 390. It should be appreciated thatother combinations of these, and other, features and trigger elementsmay be included in other embodiments.

In one embodiment, graph 389 b does not display if the current glucosevalue is unavailable. Instead, a screen indicating that the glucoseresults are unavailable is displayed.

In one embodiment, graph 389 b displays the past resulting readings fora given time period. The total time period may be sectionalized into afirst predetermined period of time 389 d, and a second predeterminedperiod of time 389 f. The second predetermined period 389 f issubsequent to the first predetermined period of time 389 d and includesmore recent readings than the first predetermined period of time 389 d.For example, in the embodiment shown, at time 10:23 pm, graph 389 bdisplays readings in a first predetermined time period 389 d of 8 hours(e.g., 2 pm to 10 pm), and also displays more recent readings within thesecond predetermined time period 389 f of 1 hour (e.g., 10 pm to 11 pm).As graph 389 b is displayed at 10:23 pm, readings for the last 23minutes (e.g., 10 pm to 10:23 pm) are shown in the second predeterminedtime period 389 f As subsequent readings are taken, graph 389 b willtrack the readings within the second predetermined time period 389 f.Once subsequent readings are taken for the entire second predeterminedperiod of time 389 f, the entire plot of readings is shifted in time bythe second predetermined period of time 389 f (e.g., 1 hour). In otherwords, once subsequent readings are obtained up to 11 pm, the plot ofreadings from 3 pm to 11 pm will shift to the first predetermined periodof time 389 d, and the second predetermined time period 389 f will beginwithout any readings and start to track subsequent readings between 11pm and 12 pm. Once subsequent readings are obtained up to 12 pm, thenentire plot of readings is again shifted by the second predeterminedperiod of time 389 f (e.g., 1 hour), and the process repeats.

In one embodiment, when scanning is first started and no data has beenobtained for the graph 389 b, the graph 389 b is not displayed until thedevice has obtained sensor readings for at least the first predeterminedperiod of time 389 d (e.g., 8 hours).

Thus, graph 389 b begins with readings for at least the entire firstpredetermined period of time 389 d. For example, in one embodiment, thisthreshold time period is equal to the first predetermined period of time389 d. In another embodiment, the threshold time period is longer thanthe first predetermined period of time such that sensor readings havebeen obtained for part or all of the second predetermined period oftime.

It is appreciated that in other embodiments, a template of the graph maybe displayed at first, but no sensor readings are shown on the graphuntil the device has obtained sensor readings for at least the firstpredetermined period of time 389 d.

Non-Actionable Reading

FIG. 10B illustrates an example Results Non-Actionable screen 394,according to one embodiment. When a scan is performed and the resultingreading is non-actionable, a Results Non-Actionable screen 394 indicatesto the user that the result is non-actionable and that the result shouldbe confirmed. For example, a non-actionable result is a reading that isdetermined to be too high or too low for a therapy treatment, decision,or recommendation to be made—e.g., an insulin calculation. Screen 394includes a trigger element for providing more information to the userregarding the non-actionable reading. When selected by the user, aNon-Actionable Message screen 396 is provided with additional details,recommendations, etc., such as recommending that the user take a teststrip measurement before making any treatment decisions. Userconfirmation (e.g., by touching the “OK” button 396 a) will return theuser to the previously displayed Results screen. In certain embodiments,a Results Non-Actionable screen may also include additional icons asdescribed below, such as a high glucose icon as illustrated in FIG. 10M.FIG. 10M illustrates a display screen 394 a including both a ResultsNon-Actionable icon and a High Glucose icon.

Results—Masked Mode

FIG. 10C illustrates an example Results—Masked screen 398, according toone embodiment. When a scan is performed while the device is set for theMasked Mode, a Results—Masked screen 398 is displayed and indicates tothe user that the reading was successful. Screen 398 does not providethe resulting reading to the user. The resulting reading is stored alongwith resulting readings from other scans in the device. These storedreadings can later be accessed by a physician or other health careprofessional at a later time. For example, the physician or HCP maydownload the data during the next patient visit (e.g., via a wired orwireless connection between the reader and the physician's or HCP'scomputer); or the data may be transferred via the internet from thereader (or patient's PC) to the physician's or HCP's computer or server;etc.

Sensor Temperature (Too Hot/Too Cold)

FIG. 10D illustrates an interface for indicating that the sensortemperature is too high, according to one embodiment. The Results SensorTemp High screen 402 is displayed to indicate to the user that thesensor temperature is too high, such as with respect to a predetermined“safe” range of temperatures. For example, screen 402 may have a warningmessage and/or icon indicating a high sensor temperature and may furtherindicate that a glucose reading is not available, as shown. Screen 402provides a trigger element 402 a for providing additional informationregarding the high sensor temperature. For example, when the usertouches the touch-sensitive button 402 a, another screen 404 isdisplayed to provide additional details or information, such as that thesensor temperature is too high and that the user should try again later.

FIG. 10E illustrates an interface for indicating that the sensortemperature is too low, according to one embodiment. The Results SensorTemp Low screen 406 is displayed to indicate to the user that the sensortemperature is too low, such as with respect to a predetermined “safe”range of temperatures. For example, screen 406 may have a warningmessage and/or icon indicating a low sensor temperature and may furtherindicate that a glucose reading is not available, as shown. Screen 406provides a trigger element 406 a for providing additional informationregarding the high sensor temperature. For example, when the usertouches the touch-sensitive button 406 a, another screen 408 isdisplayed to provide additional details or information, such as that thesensor temperature is too high and that the user should try again later.

Out of Range High/Low Readings

FIG. 10F illustrates an interface for indicating that the sensor readingis out of range, according to one embodiment. The Results Sensor HIscreen 412 is displayed to indicate to the user that the sensor readingis too high and out of range of readings. Instead of a sensor readingbeing displayed, screen 412 displays an indicator element 412 a, such asa message, icon, symbol, etc. For example, in the embodiment shown, theterm “HI” 412 a is shown in place of a sensor reading to indicate thatthe reading is out of range and too high.

The predetermined upper threshold reading value may be determined basedon a predetermined number (e.g., 500 mg/dL), or may be determinedrelative to a predetermined “acceptable” range of readings to display(e.g., 40 mg/dL to 500 mg/dL), or with respect to a target range (e.g.,350 mg/dL over the target range), etc.

Screen 412 may also include a graph 412 b of sensor readings that alsoindicates a target range 412D. Screen 412 provides a trigger element 412c for providing additional information, warning, instructions, etc.,regarding the out of range and high sensor reading. For example, whenthe user touches the touch-sensitive button 412 c, another screen 414 isdisplayed to provide additional details or information, such as that theglucose level is out of range high, that a high glucose level may bedangerous, and that the user should check again later and treat asrecommended by their health care professional.

If at screen 556, blood is applied to the test strip, asshown by block 564, then it is determined if there was sufficient bloodapplied to accurately perform a test measurement, as shown by block 566and reference path I. It should be appreciated that the timing of thisdetermination may vary. If not enough blood is present, then theStrip/Hardware Errors interface is displayed to indicate that not enoughblood was applied or that there was an error, as shown by block 568.

If it is determined that sufficient blood has been applied to the teststrip, then a Waiting interface 570 is displayed while a testmeasurement is being performed. At block 572, it is determined if theresults are ready. If ready, then the Strips Test Results screen 576 isdisplayed to indicate the resulting reading. If not ready (e.g., after apredetermined timeout period), then the Strip/Hardware Errors screen 574is displayed to indicate that there was an error in calculating ameasurement. In certain embodiments, the device may also perform a lowbattery test prior to displaying the results as described above inconjunction with FIG. 8 .

Ketone Strip Test Results Interface

In some aspects of the present disclosure, a graphical user interface isprovided that may be utilized in connection with a reader as describedherein and which functions generally to provide ketone strip testresults.

Results Screen

FIG. 14A illustrates an example Ketone Results screen 580, according toone embodiment. Screen 580 may be provided, for example, after a ketonetest strip measurement has been successfully performed. The exampleKetone Results screen 580 is shown to include a ketone test stripmeasurement 580 a and various analyte and device related information,such as indicator elements for indicating the ketone strip test 580 b,indicating the current time 580 d, indicating the battery life 580 e,etc. In one embodiment, the indicator element 580 b for identifying theketone test strip measurement is the same symbol as the indicatorelement for a blood glucose test strip measurement. In such case, theindicator element 580 b is generally indicating a test strip measurementresult versus a sensor reading result. It should be appreciated that inother embodiments, different indicator elements may be used for theketone strip test and the blood glucose strip test to distinguishbetween the two tests.

A trigger element 580 c for navigating to the Notes interface is alsoprovided to take the user to the Notes screen as shown by block 582. Itshould be appreciated that other combinations of these, and other,features and trigger elements may be included in other embodiments.

In one embodiment, the insulin calculator is enabled if the setting isenabled and if both of the following are met: 1) the ketone test hasbeen performed within a predetermined period of time (e.g., 15 minutes)of successful strip test or another predetermined period of time (e.g.,3 minutes) of a successful sensor test; and 2) insulin was not loggedwith that recent glucose test. Unless both conditions are met, theinsulin calculator button is not provided.

Control Solution Screen

FIG. 14B illustrates an example interface for indicating the results ofa ketone control solution test, according to one embodiment. The KetoneControl Solution Results screen 584 includes the results 584 a of aketone control solution test and various analyte and device relatedinformation, such as indicator elements for indicating a controlsolution test 584 b, indicating the current time 584 d, indicating thebattery life 584 e, etc. In one embodiment, the indicator element 584 bfor identifying the ketone control solution test is the same symbol asthe indicator element for a blood glucose control solution test. In suchcase, the indicator element 584 b is generally indicating a controlsolution test. It should be appreciated that in other embodiments,different indicator elements may be used for the ketone control solutiontest and the blood glucose control solution test to distinguish betweenthe two tests.

Reader Temperature Warning (Too Hot/Too Cold) Screen

FIG. 14C illustrates example interfaces for indicating that the analytemonitoring device's temperature is too high or too low, according to oneembodiment. Results Ketone Temp High2/Low2 screen 588 is displayed toindicate to the user that the device temperature is either too high ortoo low to provide a ketone reading, such as with respect to apredetermined “safe” range of temperatures to perform an accurate ketonetest measurement. For example, screen 588 may have a warning messageand/or icon 588 a indicating too high or too low of a temperature andmay further indicate that a ketone reading is not available, as shown.Screen 588 provides a trigger element 588 b for providing additionalinformation regarding the too high or too low device temperature. Forexample, when the user touches the touch-sensitive button 588 b, anotherscreen 590 or 592 is displayed to provide additional details orinformation, such as that the device temperature is too low or too high,respectively, and that the user should try again later.

Results Ketone Temp High1/Low1 screen 594 is an example interface thatis displayed when a ketone test measurement is available, but alsoindicates to the user that the device temperature is either high or low,such as with respect to a predetermined “safe” range of temperatures.For example, screen 594 displays the resulting test measurement 594 aand also displays a warning message and/or icon 594 b indicating a highor low device temperature. Icon 502 b also serves as a trigger elementfor providing additional information regarding the high or low devicetemperature. For example, when the user touches the touch-sensitivebutton 502 b, another screen 598 or 596 is displayed to provideadditional details or information, such as that the device temperatureis too low or too high, respectively, and that the user should try againlater.

Out of Range High Screen

FIG. 14D illustrates an interface for indicating that the measurementreading is out of range, according to one embodiment. The Ketone ResultsOut of Range High screen 602 is displayed to indicate to the user thatthe ketone measurement reading is too high and out of range of readings.Instead of a ketone measurement reading being displayed, screen 602displays an indicator element 602 a, such as a message, icon, symbol,etc. For example, in the embodiment shown, the term “HI” 602 a is shownin place of a measurement reading to indicate that the reading is out ofrange and too high.

The predetermined upper threshold reading value may be determined basedon a predetermined number, or may be determined relative to apredetermined “acceptable” range of readings to display, or with respectto a target range, etc.

Screen 602 provides a trigger element 602 b for providing additionalinformation, warning, instructions, etc., regarding the out of range andhigh ketone measurement reading. For example, when the user touches thetouch-sensitive button 602 b, another screen 604 is displayed to provideadditional details or information, such as that the ketone level is outof range high, that a high ketone level may be dangerous, and that theuser should check again later and treat as recommended by their healthcare professional. Upon user confirmation (e.g., via selection of the“OK” button) the user is taken back to screen 602.

High Ketones Screen

FIG. 14E illustrates an interface for indicating that the ketonemeasurement reading is high, according to one embodiment. The KetoneResult—High Ketones screen 608 is displayed to indicate to the user thatthe ketone measurement reading is a high reading, such as via a message,icon, symbol, trigger element, etc., 608 c.

The predetermined upper threshold reading value may be determined basedon a predetermined number, or may be determined relative to apredetermined range of readings, or with respect to a target range, etc.

In the embodiment shown, after a high ketone reading is obtained, screen608 is displayed and the measurement reading 608 a is shown. In additionto showing the sensor reading 608 a, screen 608 includes a triggerelement 608 c for indicating the high ketone reading and for accessingadditional information, warning, instructions, etc., regarding the highmeasurement reading. For example, when the user touches thetouch-sensitive button 608 c, another screen 610 or 612 is displayed toprovide additional details or information about the high reading, suchas that the ketone level is high, that a high ketone level may bedangerous, and that the user should check again later and treat asrecommended by their health care professional. In the embodiment shown,screen 610 is displayed if the ketone reading is between a predeterminedrange (e.g., 0.6 to 1.5) and the second screen 612 is displayed if theketone reading is between a high predetermined range (e.g., 1.6 to 8).

Screen 608 may also include an indicator element (e.g., icon, symbol,etc.) 608 b that indicates that the measurement reading pertains to astrip test measurement (e.g., ketone test strip measurement). In theembodiment shown, a symbol of a blood drop 608 b is used. Screen 608 mayalso include other trigger elements, such as a trigger element 608 e forinitiating the Notes interface.

Notes Interface

An exemplary embodiment of a graphical user interface which may beutilized in connection with a Reader as described herein and whichfacilitates a Notes procedure 3000 for entering notes into the logbookis provided. This graphical user interface is now described in greaterdetail with reference to FIG. 15 .

A graphical user interface which facilitates the Notes procedure 3000 ofthe reader may include two different notes interfaces; a first notesinterface for embodiments where the insulin calculator is disabled 3002,and a second notes interface for embodiments where the insulincalculator is enabled 3004. The Note (Insulin Calculator Disabled)Interface 3002, shown in FIG. 15A, begins with the display of an “Add toLogbook” screen 3006. This “Add to Logbook” screen 3006 includes a listof several different notes that may be entered into the Logbook. Thelist of user selectable notes may include default (e.g., preset notes)and, in some instances, custom (e.g., user-defined) notes. For example,the default notes may include one or more of the following: rapid-actinginsulin 3008, long-acting insulin 3010, food 3012, exercise 3014, andmedication 3016. The custom notes may include any notes generated by theuser through the associated informatics software. In some cases, 12notes may be included in the list of user-selectable notes. For example,5 default notes and 7 custom notes may be included. In certainembodiments, 4 user-selectable notes are displayed on the touchscreen atonce. If there are more than 4 user-selectable notes, the list of notesmay be scrolled as necessary to view the list using scroll touchscreenbuttons, such as down arrow (e.g., down triangle) touchscreen button3018 and up arrow (e.g., up triangle) touchscreen button 3020. One ormore user-selectable notes may be selected by touching the touchscreencheckbox adjacent the note desired to be selected. Touching atouchscreen checkbox will toggle the checkbox from a checked tounchecked state indicating whether the associated not is selected or notselected, respectively. For instance, the rapid-acting insulin note maybe selected by touching the touchscreen checkbox 3022, which thendisplays a check mark in the touchscreen checkbox to indicate that therapid-acting insulin note has been selected. The other user-selectablenotes may be selected or unselected (e.g., checked or unchecked) asdesired in an analogous manner.

The selection of notes may be saved by touching the “OK” touchscreenbutton 3024, which saves the selection of user-selectable notes andreturns the graphical user interface to the previous screen. If the “OK”touchscreen button 3024 is pressed without changing the selection ofuser-selectable notes, then the previous selection of user-selectablenotes is retained and saved.

In some embodiments, the amount of rapid-acting insulin, long-actinginsulin, food, exercise, and medication may be entered by touching thenumerical input touchscreen button (e.g., the “1 2 3” touchscreenbutton) associated with the desired selection. In some cases, thenumerical input touchscreen button may not be displayed if thecorresponding touchscreen checkbox is not checked, and may only bedisplayed if the corresponding touchscreen checkbox is checked. Forexample, when rapid-acting insulin checkbox 3008 is unchecked, thenumerical input touchscreen button 3026 for rapid-acting insulin is notdisplayed. When the rapid-acting insulin checkbox is checked 3022, thenumerical input touchscreen button 3026 for rapid-acting insulin isdisplayed and may be selected.

The amount of rapid-acting insulin may be entered by pressing thenumerical input touchscreen button 3026 associated with the rapid-actinginsulin note selection. Pressing the numerical input touchscreen button3026 for rapid-acting insulin will cause a numerical input screen 3028for rapid acting insulin (e.g., the “Enter Rapid-Acting Insulin” screen)to be displayed, as shown by reference path (J) (see FIG. 15B). In thenumerical input screen 3028 for rapid-acting insulin, the amount (e.g.,units) of rapid-acting insulin may be entered. The numerical inputscreen initially displays no value (e.g., “- -” is displayed in place ofany numbers), however, the amount of rapid-acting insulin may beadjusted by pressing the up arrow 3030 (e.g., “+”) touchscreen button orthe down arrow 3032 (e.g., “−”) touchscreen button to increase ordecrease, respectively, the amount of rapid-acting insulin as desired.For example, the amount of rapid-acting insulin 3034 may be adjusted by1 unit increments by tapping the up arrow 3030 or the down arrow 3032.In some embodiments, the amount increases or decreases as appropriate ata slow-rate for the first 2 seconds and at a faster rate after 2 secondswhen the up or down arrow is pressed and held. Once the desired amountof rapid-acting insulin is entered, the amount may be saved by pressingthe “OK” touchscreen button 3036, which saves the entered amount ofrapid-acting insulin and then returns the graphical user interface tothe “Add to Logbook” screen 3006, as shown by reference path (J).Numerical values for long-acting insulin may be entered in an analogousmanner by pressing the numerical input touchscreen button 3038 (e.g.,the “1 2 3” touchscreen button) associated with the long-acting insulinselection on the “Add to Logbook” screen 3006.

Numerical values for food may be entered by pressing the numerical inputtouchscreen button 3040 (e.g., the “1 2 3” touchscreen button)associated with the food selection on the “Add to Logbook” screen 3006.Pressing the numerical input touchscreen button 3040 for food will causea numerical input screen 3042 for carbohydrates to be displayed (e.g.,the “Enter Carbs” screen), as shown by reference path (J) (see FIG.15C). In the numerical input screen 3042 for food, the amount (e.g.,grams) of carbs may be entered. The numerical input screen initiallydisplays no value (e.g., “- -” is displayed in place of any numbers),however, the amount of carbs may be adjusted by pressing the up arrow3044 (e.g., “+”) touchscreen button or the down arrow 3046 (e.g., “−”)touchscreen button to increase or decrease, respectively, the amount ofcarbs as desired. For example, the amount of carbs 3048 may be adjustedby 1 gram increments by tapping the up arrow 3044 or the down arrow3046. In some embodiments, the amount increases or decreases asappropriate at a slow-rate for the first 2 seconds and at a faster rateafter 2 seconds when the up or down arrow is pressed and held. Once thedesired amount of carbs is entered, the amount may be saved by pressingthe “OK” touchscreen button 3050, which saves the entered amount ofcarbs and then returns the graphical user interface to the “Add toLogbook” screen 3006, as shown by reference path (J).

In certain embodiments, instead of entering the amount of food as gramsof carbs, the amount of food may be entered as servings of carbs, asshown in FIG. 15E. In the numerical input screen 3068 for servings ofcarbs, the screen initially displays no value (e.g., “- -” is displayedin place of any numbers), however, the servings of carbs may be adjustedby pressing the up arrow 3070 (e.g., “+”) touchscreen button or the downarrow 3072 (e.g., “−”) touchscreen button to increase or decrease,respectively, the servings of carbs as desired. For example, theservings of carbs 3074 may be adjusted by 0.5 serving increments bytapping the up arrow 3070 or the down arrow 3072. In some embodiments,the amount increases or decreases as appropriate at a slow-rate for thefirst 2 seconds and at a faster rate after 2 seconds when the up or downarrow is pressed and held. In some cases, the numerical input screen3068 for servings of carbs may include a display of the grams of carbs3076 that corresponds to the number of servings entered. In some cases,the numerical input screen 3068 for servings of carbs may include adisplay of the energy (e.g., kcal) of carbs 3078 that corresponds to thenumber of servings entered. Once the desired servings of carbs isentered, the value may be saved by pressing the “OK” touchscreen button3080, which saves the entered servings of carbs and then returns thegraphical user interface to the “Add to Logbook” screen 3006.

Referring back to the numerical input screen 3042 for the amount (e.g.,grams) of carbs (see FIG. 15C), the numerical input screen 3042 alsoincludes two touchscreen checkboxes configured to allow the selection ofreminders to check a user's glucose. For example, the numerical inputscreen 3042 includes a “1 hr” touchscreen checkbox 3052 and a “2 hr”touchscreen checkbox 3054. None, one or both of the touchscreencheckboxes may be selected as desired. Pressing the “1 hr” touchscreencheckbox 3052 will display a check mark in the “1 hr” touchscreencheckbox 3052 indicating that the “1 hr” touchscreen checkbox 3052 hasbeen selected and will set the Reader to alert the user to check theuser's glucose level after 1 hour. Pressing the “2 hr” touchscreencheckbox 3054 will display a check mark in the “2 hr” touchscreencheckbox 3054 indicating that the “2 hr” touchscreen checkbox 3054 hasbeen selected and will set the Reader to alert the user to check theuser's glucose level after 2 hours. The check glucose remindercheckboxes may also be displayed on the numerical input screen 3068 forentering the servings of carbs as described above (see FIG. 15E).

As indicated above, a second notes interface may be provided forembodiments where the insulin calculator is enabled 3004. The Note(Insulin Calculator Enabled) Interface 3004, shown in FIG. 15D, beginswith the display of an “Add to Logbook” screen 3056. This “Add toLogbook” screen 3056 includes a list of several different notes that maybe entered into the Logbook, similar to the “Add to Logbook” screen 3006in the Note (Insulin Calculator Disabled) Interface 3002 describedabove. In the “Add to Logbook” screen 3056 of the Note (InsulinCalculator Enabled) Interface 3004, the user-selectable notes (e.g.,default and custom notes) may be selected (e.g., checked) or unselected(e.g., unchecked) as desired in an analogous manner as described abovein relation to the Note (Insulin Calculator Disabled) Interface 3002. Inaddition, the numerical input touchscreen buttons (e.g., the “1 2 3”touchscreen buttons) of the Note (Insulin Calculator Enabled) Interface3004 function in an analogous manner as described above in relation tothe Note (Insulin Calculator Disabled) Interface 3002.

In the Note (Insulin Calculator Enabled) Interface 3004, the insulin onboard and rapid-acting insulin calculator features of the graphical userinterface are enabled. For instance, in the Note (Insulin CalculatorEnabled) Interface 3004, rather than displaying a numerical inputtouchscreen button for rapid-acting insulin, a calculator touchscreenbutton 3058 is displayed with the rapid-acting insulin selection.Pressing the calculator touchscreen button 3058 will cause the graphicaluser interface to display the Insulin on Board Interface 3060 (see FIG.16 ) and the Insulin Calculator Interface 3062 (see FIG. 17 ). In someembodiments, if food information (e.g., amount of carbs) is entered asdescribed above, then when the calculator touchscreen button 3058 ispressed, the amount of carbs that was previously entered willautomatically be displayed in the corresponding insulin on board andcalculator interface screens.

In certain embodiments, the Notes—From Logbook Entry Interface 3064 maybe displayed from the Logbook Entry screen if the “add or edit notes”touchscreen button is pressed. The Notes—From Logbook Entry Interface3064 begins with the display of an “Add to Logbook” screen 3066. This“Add to Logbook” screen 3066 includes a list of several differentuser-selectable notes that may be entered into the Logbook, similar touser-selectable notes described above. In certain embodiments, the “Addto Logbook” screen 3066 of the Notes—From Logbook Entry Interface 3064does not include a user-selectable note for rapid-acting insulin orfood. The other default notes (e.g., long-acting insulin, exercise,medication) and custom notes may still be available for selection by theuser as desired.

Insulin on Board Interface

As described above, pressing the calculator touchscreen button 3058 fromthe “Add to Logbook” screen 3056 of the Notes (Insulin CalculatorEnabled) Interface 3004, will cause the graphical user interface todisplay the Insulin on Board Interface 3060 (see FIG. 16 ). RegardingFIG. 16A, in certain embodiments, a user's insulin on board (JOB)information is used in the calculation of a recommended rapid-actinginsulin dosage amount. For example, if an insulin dosage has been logged(e.g., logged as a calculated dose, or entered into the logbook as arapid-acting dose), then the insulin dosage information may be used inthe calculation of a recommended rapid-acting insulin dosage amount3082.

In certain embodiments, a user's insulin on board information is used inthe calculation of a recommended rapid-acting insulin dosage amount ifthe user's most recent insulin dose was administered within a certaintime period. In some instances, the insulin calculator may be partiallylocked out if the difference between the current time and the time themost recent rapid-acting insulin was administered is less than a lockout time period (e.g., the most recent insulin dose was administeredwithin a preceding lockout time period, such as within the past 2hours). During the lockout time period, the insulin calculator may beprogrammed to only calculate a meal bolus and may not calculate anadditional correction bolus 3084. During the lockout time period, theinsulin calculator may not include insulin on board into the calculationof a meal bolus.

If the difference between the current time and the time the most recentinsulin bolus was administered is greater than a threshold time period(e.g., the lockout time period) and less than the duration of insulinaction, then the insulin calculator may be programmed to include theuser's IOB into the calculation of the recommended rapid-acting insulindosage amount 3086. In the time period between the end of the lockouttime period and the end of the user's duration of insulin action, theinsulin calculator may be programmed to determine the recommendedrapid-acting insulin dosage amount based on the determined analyteconcentration and the insulin on board information. For instance, in thetime period between the end of the lockout time period and the end ofthe user's duration of insulin action, the insulin calculator may beprogrammed to subtract the user's IOB from the rapid-acting insulindosage based upon the current glucose concentration level to determinethe recommended rapid-acting insulin dosage amount.

In certain instances, if the difference between the current time and thetime the most recent insulin bolus was administered is greater than theuser's duration of insulin action, then the insulin calculator will notinclude insulin on board into the calculation of a recommendedrapid-acting insulin dosage amount 3088. In the time period after theuser's duration of insulin action has expired (and before the next doseof insulin is administered), the insulin calculator may assume theuser's insulin on board is zero. In the time period after the user'sduration of insulin action has expired (and before the next dose ofinsulin is administered), the insulin calculator may be programmed todetermine the rapid-acting insulin dosage amount based on the determinedglucose concentration (without including the insulin on boardinformation).

Regarding FIG. 16B, the Insulin on Board Interface is shown, and beginswith a prompt screen 3090 prompting the user with a question asking ifthe user has forgotten to log any rapid-acting insulin the user hastaken since a prior predetermined time point. The prior predeterminedtime point corresponds to the most recent of either: (a) the currenttime minus the set insulin duration of action, or (b) the time of thelast logged dose of rapid-acting insulin. The prompt screen 3090 has a“Yes” touchscreen button 3092 and a “No” touchscreen button 3094 toselect a yes or no answer to the prompted question. If the “No”touchscreen button 3094 is pressed, then the graphical user interfacedisplays the Insulin Calculator Interface 3062 (see FIG. 17 ). If the“Yes” touchscreen button is pressed, then the graphical user interfacedisplays a numerical input screen 3096 in the Insulin on BoardInterface. On the numerical input screen 3096, the amount ofrapid-acting insulin that the user has forgotten to log since the priorpredetermined time point may be entered. The amount (e.g., units) ofrapid-acting insulin may be adjusted by pressing the up arrow 3098(e.g., “+”) touchscreen button or the down arrow 3100 (e.g., “−”)touchscreen button to increase or decrease, respectively, the amount ofrapid acting insulin as desired. For example, the amount of rapid actinginsulin 3102 may be adjusted by 1 unit increments by tapping the uparrow 3098 or the down arrow 3100. In some embodiments, the amount ofrapid-acting insulin may be adjusted by 0.5 unit increments (not shown)if the calculator is set to allow half-unit increments. In someembodiments, the amount increases or decreases as appropriate at aslow-rate for the first 2 seconds and at a faster rate after 2 secondswhen the up or down arrow is pressed and held. Numerical input screenmay also include a “?” touchscreen button 3104, which, when pressed,provides a help screen 3106 that includes additional instructions to theuser. For example, the help screen 3106 may instruct the user to enterthe sum total of insulin units that the user has taken over the last Xhours that the user has not already logged, where X is the insulinduration of action time. The help screen 3106 may also inform the userthat the Reader will use the entered amount of rapid-acting insulin tocalculate the user's next rapid-acting insulin dose. The help screen3106 includes an “OK” touchscreen button 3108, which, when pressed,returns the display to the numerical input screen 3096.

On the numerical input screen 3096, once the desired amount ofrapid-acting insulin has been entered, the “Next” touchscreen button3110 may be pressed to advance the graphical user interface to a timeinput screen 3114, as shown by reference path (M) (see FIG. 16C).Alternatively, on the numerical input screen 3096, the “Back”touchscreen button 3112 may be pressed, which returns the graphical userinterface to the prompt screen 3090.

Regarding FIG. 16C, on the time input screen 3114, the display presentsa question asking the user how long ago was the unlogged dose ofrapid-acting insulin. On the time input screen 3114, the time since thelast unlogged rapid-acting insulin dose may be adjusted by pressing theup arrow 3116 (e.g., “+”) touchscreen button or the down arrow 3118(e.g., “−”) touchscreen button to increase or decrease, respectively,the time as desired. For example, the time 3120 may be adjusted by 15minute increments by tapping the up arrow 3116 or the down arrow 3118.In some embodiments, the amount increases or decreases as appropriate ata slow-rate for the first 2 seconds and at a faster rate after 2 secondswhen the up or down arrow is pressed and held. In some instances, thedefault time is 15 minutes (e.g., displayed as “15 minutes or less”). Insome cases, the maximum time is the time value set for the insulinduration of action. If the user presses the up arrow 3116 once while thetime is at the maximum value, then the time displayed may be shown as“[insulin duration] hours or more”, and the up arrow 3116 may bedisplayed as greyed out and may be un-selectable by the user.

The time input screen 3114 also includes a “?” touchscreen button 3122,which, when pressed, provides a help screen 3106 that includesadditional instructions to the user as described above and as indicatedby reference path (K). The time input screen includes a “Back”touchscreen button 3124, which, when pressed, returns the display to thenumerical input screen 3096 as shown by reference path (L). Once thedesired time since the last unlogged rapid-acting insulin dose has beenentered on the time input screen 3114, the “Next” touchscreen button3126 may be pressed to advance the graphical user interface to the nextscreen in the Insulin on Board Interface, such as screen 3128. Pressingthe “Next” touchscreen button will save the entered rapid-acting insulindose with a time stamp reflecting the time calculated based on theinterval since the dose was taken as indicated by the user in theprevious time input screen 3114. Screen 3128 informs the user that theentered dose of rapid-acting insulin will be used in the calculation ofthe user's suggested insulin dose, and that the next screen will allowthe user to enter what the user plans to eat. Screen 3128 includes a“Back” touchscreen button 3130, which, when pressed, returns the displayto the time input screen 3114. Screen 3128 includes a “Next” touchscreenbutton 3132, which, when pressed, causes the graphical user interface todisplay the Insulin Calculator Interface 3062 (see FIG. 17 ).

Insulin Calculator Interface

An Insulin Calculator Interface 3062 begins with the display of an“Enter Carbs” screen (see FIG. 17B). On the “Enter Carbs” screen, theamount of carbs may be entered. The amount of carbs may be entered asgrams, servings, or by meal, depending on the settings of the Reader.

For example, the amount of carbs may be entered as grams of carbs on the“Enter Carbs” (grams) screen 3200. The “Enter Carbs” (grams) screen 3200initially displays no value (e.g., “- -” or “0” is displayed), however,the grams of carbs may be adjusted by pressing the up arrow 3202 (e.g.,“+”) touchscreen button or the down arrow 3204 (e.g., “−”) touchscreenbutton to increase or decrease, respectively, the grams of carbs asdesired, as shown by reference path (T) (see FIG. 17C). For example, thegrams of carbs 3206 may be adjusted by 1 gram increments by tapping theup arrow 3202 or the down arrow 3204. In some cases, the minimum gramsof carbs that may be entered is zero carbs, and the maximum grams ofcarbs that may be entered is 200 grams of carbs. In some embodiments,the amount increases or decreases as appropriate at a slow-rate for thefirst 2 seconds and at a faster rate after 2 seconds when the up or downarrow is pressed and held. Once the desired amount is entered, theamount may be saved by pressing the “Done” touchscreen button 3208,which saves the entered grams of carbs and then advances the graphicaluser interface to the Insulin Calculation Interface 3212, as shown byreference paths (S and V) (see FIGS. 17B, 17C and 17E). The “EnterCarbs” (grams) screen 3200 includes a “Back” touchscreen button 3210,which, when pressed, returns the display to the Results screen.

In certain embodiments, the amount of carbs may be entered as servingsof carbs on the “Enter Carbs” (servings) screen 3216. The “Enter Carbs”(servings) screen 3216 initially displays no value (e.g., “- -” or “0”or “0.0” is displayed), however, the servings of carbs may be adjustedby pressing the up arrow 3218 (e.g., “+”) touchscreen button or the downarrow 3220 (e.g., “−”) touchscreen button to increase or decrease,respectively, the servings of carbs as desired, as shown by referencepath (T) (see FIG. 17C). For example, the servings of carbs 3222 may beadjusted by 0.5 serving increments by tapping the up arrow 3218 or thedown arrow 3220. In some cases, the minimum servings of carbs that maybe entered is zero servings. In some instances, the serving size may beset to 10 or 12 grams of carbs per serving and the maximum servings ofcarbs that may be entered is 20 servings. In some instances, the servingsize may be set to 15 grams of carbs per serving and the maximumservings of carbs that may be entered is 15 servings. In someembodiments, the amount increases or decreases as appropriate at aslow-rate for the first 2 seconds and at a faster rate after 2 secondswhen the up or down arrow is pressed and held. In some cases, the “EnterCarbs” (servings) screen 3216 may include a display of the grams ofcarbs 3228 that corresponds to the number of servings entered (see FIG.17C). In some cases, the “Enter Carbs” (servings) screen 3216 mayinclude a display of the energy (e.g., kcal) of carbs 3230 thatcorresponds to the number of servings entered (see FIG. 17C). Once thedesired amount is entered, the amount may be saved by pressing the“Done” touchscreen button 3224, which saves the entered servings ofcarbs and then advances the graphical user interface to the InsulinCalculation Interface 3212, as shown by reference paths (S and V) (seeFIGS. 17B, 17C and 17E). The “Enter Carbs” (servings) screen 3216includes a “Back” touchscreen button 3226, which, when pressed, returnsthe display to the Results screen.

In certain embodiments, the amount of carbs may be entered by meal onthe “Enter Carbs” (meal) screen 3232. The “Enter Carbs” (meal) screen3232 displays a list of meals, such as breakfast, lunch, dinner, or nomeal. Each selection includes a corresponding touchscreen radio button.For example, to select the “Dinner” meal, the touchscreen radio button3234 associated with the “Dinner” selection may be pressed. The “EnterCarbs” (meal) screen 3232 includes a “Back” touchscreen button 3238,which, when pressed, returns the display to the Results screen.

The “Double Check” screen 3240 (see FIG. 17C) is displayed if the userhas marked the same meal since midnight (12:00 AM) of the current day.The “Double Check” screen 3240 displays a warning to the user indicatingthat the user has already logged insulin for the selected meal that day,and asks the user if the user wants to log more insulin for the samemeal that day. The “Double Check” screen 3240 includes a “No”touchscreen button, which, when pressed, returns the graphical userinterface to the “Enter Carbs” (meal) screen 3232 via reference path(A1). The “Double Check” screen 3240 includes a “Yes” touchscreenbutton, which, when pressed, advances the graphical user interface tothe Insulin Calculation Interface 3212 via reference path (Q) (see FIG.17E).

Referring again to FIG. 17B, the “Enter “Carbs” screens (e.g., the“Enter Carbs” (grams) screen 3200, and the “Enter Carbs” (servings)screen 3216) both include a “?” touchscreen button 3214, which, whenpressed, causes the graphical user interface to display help screens3246, as shown by reference path (O) in FIG. 17B, or by reference path(N) in FIG. 17C. Help screens 3246 (see FIG. 17A) may displayinformation to the user depending on whether the Reader is set todisplay carbs as grams, servings by grams of carbs, or servings by kcalof carbs. For example, a help screen 3248 may be shown that displays aset of help information to the user regarding carbohydrates when theReader is set to display carbs as grams. In other instances, the helpscreen 3250 may be shown that displays a different set of helpinformation to the user regarding carbohydrates as servings by grams ofcarbs when the Reader is set to display servings by grams of carbs. Inother instances, the help screen 3252 may be shown that displays yet adifferent set of help information to the user regarding carbohydrates asservings by kcal of carbs when the Reader is set to display servings bykcal of carbs. In certain instances, if the help information includesmore text than is able to be displayed on a single help screen, the helpscreen may include a down arrow 3254, which, when pressed, causes thegraphical user interface to display the remaining text on a second helpscreen 3256. The second help screen 3256 includes an up arrow 3258,which, when pressed, returns the graphical user interface to the firsthelp screen 3248, 3250 or 3252 depending on the settings of the Readeras described above. The help screens 3248, 3250, 3252 and 3256 includean “OK” touchscreen button 3260, which, when pressed, returns thegraphical user interface to the “Enter “Carbs” screen (e.g., the “EnterCarbs” (grams) screen 3200, or the “Enter Carbs” (servings) screen 3216)from which the help screen was launched, via reference path (P).

Referring to FIG. 17B, once the desired amount of carbs is entered, theamount may be saved by pressing the “Done” touchscreen button 3208 or3224, which saves the entered amount of carbs (e.g., grams of carbs orservings of carbs) and then advances the graphical user interface to theappropriate Insulin Calculation Interface 3212, as shown by referencepath (S) (see FIG. 17E). The Insulin Calculation Interface 3212 displaysthe suggested dose of insulin based on the amount of carbs entered bythe user on the previous screens as described above and/or the user'sinsulin on board, if any, as described above. The Insulin CalculationInterface 3212 may vary in appearance depending on whether the Reader isset to display whole units of insulin, half units of insulin, or adecimal point or a comma between the whole and half units of insulin.

Referring to FIG. 17E, in embodiments of the Insulin CalculationInterface 3212 where the Reader is set to display whole units ofinsulin, the Insulin Calculation Interface 3212 will appear as SuggestedDose screen 3262. Suggested Dose screen 3262 displays the suggested doseof insulin 3264 as units of insulin. The suggested dose of insulin maybe adjusted in 1 insulin unit increments by pressing the up arrow 3266(e.g., “+”) touchscreen button or the down arrow 3268 (e.g., “−”)touchscreen button to increase or decrease, respectively, the suggesteddose of insulin as desired. The minimum and maximum values for thesuggested dose of insulin are 0 and 99, respectively. If the suggesteddose of insulin is adjusted by the user from its initial value, theamount of units increased or decreased by the user 3270 will be shownbelow the suggested insulin dose 3264. If the user adjustment of thesuggested dose of insulin is calculated to reduce the user's bloodglucose below the target range, then the graphical user interface willdisplay a warning screen 3292 that displays a caution to the user thatthe insulin dose entered may take the user's blood glucose lower thanthe user's target range and put the user at risk for a low glucose event(see FIG. 17D). The warning screen 3292 includes an “OK” touchscreenbutton, which, when pressed, returns the graphical user interface to theSuggested Dose screen 3262 via reference path (W). The Suggested Dosescreen 3262 includes a “Back” touchscreen button 3272, which, whenpressed, returns the user to the prior “Enter “Carbs” screen (e.g., the“Enter Carbs” (grams) screen 3200, or the “Enter Carbs” (servings)screen 3216) via reference path (R). The Suggested Dose screen 3262 alsoincludes a “Log dose” touchscreen button 3274, which, when pressed,saves the suggested insulin dose in the logbook along with an associatedglucose test result and the time the test was taken (e.g., the insulindose is not saved as delivered at the time the “Log dose” touchscreenbutton is pressed) and advances the graphical user interface to theLogbook via reference path (Y) (see FIG. 17D).

Referring to FIG. 17E, in embodiments of the Insulin CalculationInterface 3212 where the Reader is set to display half unit incrementsof insulin and a decimal point between the whole and half units, theInsulin Calculation Interface 3212 will appear as Suggested Dose screen3276.

The suggested dose ofinsulin may be adjusted in 0.5 insulin unit increments by pressing theup arrow 3280 (e.g., “+”) touchscreen button or the down arrow 3282(e.g., “−”) touchscreen button to increase or decrease, respectively,the suggested dose of insulin as desired. The minimum and maximum valuesfor the suggested dose of insulin are 0 and 50, respectively. If thesuggested dose of insulin is adjusted by the user from its initialvalue, the amount of units increased or decreased by the user 3284 willbe shown below the suggested insulin dose 3278. If the user adjustmentof the suggested dose of insulin is calculated to reduce the user'sblood glucose below the target range, then the graphical user interfacewill display a warning screen 3292 that displays a caution to the userthat the insulin dose entered may take the user's blood glucose lowerthan the user's target range and put the user at risk for a low glucoseevent (see FIG. 17D). The warning screen 3292 includes an “OK”touchscreen button, which, when pressed, returns the graphical userinterface to the Suggested Dose screen 3276 via reference path (W). TheSuggested Dose screen 3276 includes a “Back” touchscreen button 3286,which, when pressed, returns the user to the prior “Enter “Carbs” screen(e.g., the “Enter Carbs” (grams) screen 3200, or the “Enter Carbs”(servings) screen 3216) via reference path (R). The Suggested Dosescreen 3276 also includes a “Log dose” touchscreen button 3288, which,when pressed, saves the suggested insulin dose in the logbook along withan associated glucose test result and the time the test was taken (e.g.,the insulin dose is not saved as delivered at the time the “Log dose”touchscreen button is pressed) and advances the graphical user interfaceto the Logbook via reference path (Y) (see FIG. 17D).

Referring to FIG. 17E, in embodiments of the Insulin CalculationInterface 3212 where the Reader is set to display half unit incrementsof insulin and a comma between the whole and half units, the InsulinCalculation Interface 3212 will appear as Suggested Dose screen 3290.The functions of Suggested Dose screen 3290 are analogous to thosedescribed for Suggested Dose screen 3276 above.

If the insulin calculator of the Reader determines that no insulin doseis suggested, the Insulin Calculation Interface 3212 will be displayedas No Suggested Dose screen 3298, which displays information indicatingthat based on the user's current glucose level, no rapid-acting insulinis being suggested. The No Suggested Dose screen includes a “Back”touchscreen button 3300, which, when pressed, returns the user to theprior “Enter “Carbs” screen (e.g., the “Enter Carbs” (grams) screen3200, or the “Enter Carbs” (servings) screen 3216) via reference path(R). The No Suggested Dose screen 3298 includes a “Next” touchscreenbutton 3302, which, when pressed, advances the graphical user interfaceto Suggested Dose screen 3304. Suggested Dose screen 3304 begins bydisplaying a suggested does of insulin 3306 as 0 units of insulin. Thesuggested dose of insulin may be adjusted in 1 unit or 0.5 insulin unitincrements, depending on the Reader settings, by pressing the up arrow3308 (e.g., “+”) touchscreen button or the down arrow 3310 (e.g., “−”)touchscreen button to increase or decrease, respectively, the suggesteddose of insulin as desired. If the suggested dose of insulin is adjustedby the user from its initial value, the amount of units increased ordecreased by the user will be shown below the suggested insulin dose3306. If the user adjustment of the suggested dose of insulin iscalculated to reduce the user's blood glucose below the target range,then the graphical user interface will display a warning screen 3292that displays a caution to the user that the insulin dose entered maytake the user's blood glucose lower than the user's target range and putthe user at risk for a low glucose event (see FIG. 17D). The warningscreen 3292 includes an “OK” touchscreen button, which, when pressed,returns the graphical user interface to the Suggested Dose screen 3304via reference path (W). The Suggested Dose screen 3304 includes a “Back”touchscreen button 3312, which, when pressed, returns the user to theprior No Suggested Dose screen 3298. The Suggested Dose screen 3304 alsoincludes a “Log dose” touchscreen button 3314, which, when pressed,saves the suggested insulin dose in the logbook along with an associatedglucose test result and the time the test was taken (e.g., the insulindose is not saved as delivered at the time the “Log dose” touchscreenbutton is pressed) and advances the graphical user interface to theLogbook via reference path (Y) (see FIG. 17D).

Suggested Dose screens 3262, 3276, 3290 and 3304 include a “Dosedetails” touchscreen button 3294 (e.g., an “i” touchscreen button),which, when pressed, causes graphical user interface to display DoseDetails Interface via reference path (X) (see FIG. 17D).

Dose Details Interface 3296 is shown in FIGS. 18A and 18B. Dose DetailsInterface begins a Dose Details screen (e.g., 3316, 3318 and 3320) thatdisplays a summary of the calculated insulin dose. The Dose Detailsscreen (e.g., 3316, 3318 and 3320) may have various appearancesdepending on the settings of the Reader (e.g., whether the Reader is setto display carbs as grams of carbs, servings of carbs, or by meal) andthe data input by the user or calculated by the Reader (e.g., amount ofcarbs, insulin on board, user adjustment to the suggested dose ofinsulin, etc.). The Dose Details screen displays the amount of carbs bymeal 3322, as grams of carbs 3324, or as servings of carbs 3326. Ifinsulin correction is enabled on the Reader, the Dose Details screenwill display the suggested insulin dose 3328. If insulin correction isdisabled on the Reader (e.g., the Easy setup sets “no correctioninsulin”) then the suggested insulin dose is not displayed. If theReader determines that insulin on board is present, then the DoseDetails screen displays the amount of insulin on board 3330. In theReader determines that no insulin on board is present, then the amountof insulin on board is not displayed. If the user adjusted the suggestedinsulin dose, the Dose Details screen will display the amount the useradjusted the suggested insulin dose 3332. Based on the above data, theDose Details screen displays the calculated insulin dose 3334.

The Dose Details screen includes a down arrow touchscreen button 3336,which, when pressed, advances the Dose Details screen to the second pageof the Dose Details screen via reference path (B1) (see FIG. 18B). Theinformation displayed on the second page of the Dose Details screen mayvary depending on whether insulin on board is present and whether thesuggested dose of insulin only accounts for carbs in the user's meal. Ifinsulin on board is not present, then the second page of the DoseDetails screen 3338 displays information indicating that the suggesteddose of rapid-acting insulin covers the carbs in the user's meal andcorrects for the user's current glucose level. If insulin on board ispresent and the user has taken insulin within the past 2 hours, then thesecond Dose Details screen 3340 displays information indicating that theuser has taken rapid-acting insulin in the past 2 hours, and thesuggested dose of insulin covers the carbs in the user's meal but doesnot correct for the user's current glucose level. If insulin on board ispresent and the time when the user has last taken insulin is more than 2hours from the current time but less than the duration of insulinaction, then the second Dose Details screen 3342 displays informationindicating that the user has taken rapid-acting insulin in the past 4hours, and the suggested dose of insulin covers the carbs in the user'smeal, corrects for the user's current glucose level, and accounts forinsulin that was previously logged. The second Dose Details screen(e.g., 3338. 3340 and 3342) include an up arrow touchscreen button 3344,which, when pressed, returns the graphical user interface to theprevious Dose Details screen.

Receive Reminders Interface

An exemplary embodiment of a graphical user interface which may beutilized in connection with a Reader as described herein and whichfacilitates a Receive Reminder procedure 3500 for receiving reminders isprovided. This graphical user interface is now described in greaterdetail with reference to FIG. 20 .

The Receive Reminder Interface 3500, shown in FIG. 20B, begins when areminder (e.g., a reminder that has been set using the RemindersInterface 3400 described above) is activated, such as when the time ortriggering event of a scheduled reminder is reached. A scheduledreminder should be displayed when the time/triggering event of thereminder is reached even if the Reader display is off. In certainembodiments, a scheduled reminder is not displayed on the Reader if thetime/triggering event of the reminder is reached: (1) During a bloodglucose test using a strip—instead the reminder is presented after theresults have been displayed; (2) When the battery is criticallylow—instead the reminder is presented when the battery is sufficientlycharged, and the Reader is powered on; (3) During errorconditions—instead the reminder is presented the next time the Reader ispowered on; or (4) When the Reader is connected to a computer and datatransfer is in process—instead the reminder is presented when the datatransfer is completed.

When the time/triggering event of the reminder is reached, a Reminderscreen is 3502 displayed (FIG. 20B). The Reminder screen 3502 includesdisplay of the reminder with a reminder icon 3504 representing the typeof reminder. For example, the reminder icon may be an “Alarm” remindericon 3504 (e.g., a picture of a bell or alarm clock, etc.), indicatingthat the type of reminder is an alarm. In some instances, the remindericon is a “Take Insulin” reminder icon 3506 (e.g., a picture of asyringe) (see FIG. 20A), indicating that the type of reminder is areminder to the user to take insulin. In some instances, the remindericon is a “Check Glucose” reminder icon 3508 (e.g., a picture of aglucose Reader) (see FIG. 20A), indicating that the type of reminder isa reminder to the user to check their glucose level. Other types oficons and reminders are possible.

If the Reminder sound is set to on, a beep sounds with appearance of anyreminders screen. If a reminder is ignored, the reminder will appear onthe screen with the next power on (whether by hardware button or stripinsertion). If multiple reminders are active, the reminder screens willstack up with the most recent reminder showing first. The reminderscreens will require dismissal one by one. If daily repeated remindershave been missed, once a new day's reminder is current, the previousday's reminder for that time is no longer active and is not part of thestack-up of reminder screens.

The Reminder screen 3502 includes a “Snooze 15 min” touchscreen button3510, which, when pressed, sets the active reminder to re-active in 15minutes, and returns the graphical user interface to the next activereminder or, if there are no other active reminders, to the previouslydisplayed screen before the reminder was activated. The Reminder screen3502 also includes an “OK” touchscreen button 3512, which, when pressedcancels the active reminder and returns the graphical user interface tothe next active reminder or, if there are no other active reminders,returns the graphical user interface to the Home Screen. In the Readerpowers off automatically due to a timeout while displaying the Reminderscreen, the reminder that was active when the Reader timed-out will bedisplayed again the next time the Reader is powered on.

History Menu01 screen 622 isshown in FIG. 21A and provides a menu of summary options that the usercan select. Option 622 a takes the user to a Logbook screen for viewinglogged data, as shown by block 626. Option 622 b takes the user to aDaily Graph screen which provides a summary of data in a daily graphformat. Option 622 c provides a screen for averages for glucose readingsobtained for a period of time. If more options are available that canfit on a single screen shot, then a trigger element 622 h (e.g., anarrow symbol) for scrolling or otherwise viewing the remaining optionsmay be selected. When arrow 622 h is selected, the user is taken toscreen 624 wherein the remaining options are displayed. For example,option 624 provides a summary screen of low glucose events for a periodof time. Option 622 d provides a screen showing a summary of time thatobtained readings were in the target zone. Option 622 f provides ascreen showing summarizing information related to the user of the readerdevice. Option 622 g provides a summary screen of daily patterns thathave been determined or identified based on reading acquired for aperiod of time. Trigger element 622 i takes the user back to screen 622.

When one of the options are selected, it is determined if sensor data ispresent, as shown at block 628. If no data is present, a No Sensor Datascreen 630 is displayed to indicate to the user that no sensor data isavailable for the summary. In one embodiment, the all summaries exceptfor logbook include sensor data only (e.g., glucose data obtained fromthe sensor). If the device includes only strip data and insufficientsensor data, then the No Sensor Data screen is still provided when asummary option is selected.

If sensor data is provided, then the corresponding screen for theselected summary option is displayed, as represented by reference pathT1. From the selected summary screen, the user can navigate back to themenu options screens 622,624 to select another menu option if desired,as shown by reference path S1.

FIG. 21B illustrates a Daily Graph screen 632 for showing a daily graphof sensor readings obtained over a single day or 24 hour time period.For example, the daily graph 632 illustrates the readings obtained onWednesday, February 22. The horizontal axis of graph 632 represents timethroughout the day, while the vertical axis represents sensor readingvalues. A target zone 632 d may also be provided on graph 632 torepresent the target zone for readings. Graph 632 may also include atime change icon 632 a to inform the user of a time change. Also shown,are event indicators 632 b which indicate various events with symbols oricons on the graph 632. For example, the needle icon represents a loggedinsulin event indicating that an insulin dose was taken, and the appleicon represents a logged food event indicating that food was eaten. Moredetails may be stored or logged for the given event, and in oneembodiment, the event indicators 632 b may be selected by the user toprovide additional details regarding the event.

In certain embodiments, event indicators may only be applied to glucosevalues after a glucose reading has been taken, either via the glucosesensor or a test strip reading. Event details may be input logged oradded as notes associated with glucose values or glucose events; such ashigh or low glucose levels. In certain embodiments, event details may beimported from another source (e.g., electronic diary or log) and storedin a memory device.

In the embodiment shown, trigger elements 632 c (e.g., left and rightarrows) are also provided to enable the user to navigate forwards andbackwards to another day or 24-hour time period. For example, the usercould navigate to the next day after Wednesday using the right arrow, orgo to the previous day by selecting the left arrow.

FIG. 21C illustrates an exemplary Average Glucose Summary interface forproviding a graph of sensor readings obtained over a time period that issummarized with respect to a predetermined time period such as singleday or 24 hour time period as shown. For example, Average Glucose (GLUC)01 screen provides a bar graph 634 a for sensor readings taken over thelast 7 days. The bar graph 634 a includes bars for various increments oftime throughout a single day. Each bar represents the average glucosereading that was obtained at that increment of time of day for the last7 days. For example, the average of all the sensor readings obtainedbetween 12 am and 6 am over the last 7 days, is 121 mg/dL. For 6 am to12, the average glucose reading was 152 mg/dL, etc.

Screen 634 also includes an average glucose value 634 b for the timeperiod of data. For example, the average glucose reading for allreadings obtained over the last 7 days was 119 mg/dL. Screen 634 alsoincludes a trigger element 634 c (e.g., an arrow icon) for changing thedifferent time period of obtained data. For example, if the user selectsthe right arrow icon 634 c, the user is taken to AVG GLUC02 screen 636,which similarly displays a bar graph 636 a and average glucose value 636b, but for a different time period, such as the last 14 days as shown.Similarly, screen 636 also includes trigger elements 634 c for againincreasing the time period. In this way, the user can change to AVGGLUC03 screen 638, which similarly displays a bar graph 638 a andaverage glucose value 638 b, but for a different time period, such asthe last 30 days as shown. Similarly, the user can change to AVG GLUC04screen 640, which similarly displays a bar graph 640 a and averageglucose value 640 b, but for a different time period, such as the last90 days as shown. Trigger elements 634 c enable the user to navigateforwards and backwards between screens 634,636,638,640 to change thetime periods as desired. From any of the screens, user confirmation(e.g., by selecting the “ok” button) will take the user back to theoptions menu interface 622,624.

FIG. 21D illustrates an exemplary screen for showing the percentage oftime the sensor readings were within a target zone. Time In Targetscreen 642 displays a representation 642 a of the percentage of timewithin a target zone, above a target zone, and below a target zone, forsensor readings obtained for a period of time (e.g., 7 days in theembodiment shown). Trigger element 642 c is provided to enable the userto change the time period—e.g., similarly as described in FIG. 21C.Representation 642 a also includes bar graphs for the associatedpercentages.

FIG. 21E illustrates an exemplary screen 644 for showing a graph 644 aof the number of events associated with sensor readings obtained over atime period, wherein the events are summarized with respect to apredetermined time period, such as single day or 24 hour time period asshown. For example, screen 644 indicates a graph 644 a for sensorreadings obtained over the last 7 days, wherein 1 event occurred between12 am and 6 am, 0 events occurred between 6 am and 12 pm, 3 eventsbetween 12 pm and 6 am, etc. In the embodiment shown, the eventcorresponds to a low glucose reading—e.g., with respect to a targetzone. Other events may also be implemented—e.g., high glucose readings,insulin dosages, food intake events, etc. Trigger element 644 c isprovided to enable the user to change the time period.

FIG. 21F illustrates an exemplary screen 648 for indicating informationassociated with the use of the sensor over a time period. For example,screen 648 indicates the average scans per day, and the number of dayswith sensor data, for sensor readings obtained over the last 7 days.Similarly, trigger element 648 c is provided to enable the user tochange the time period.

FIG. 21G illustrates an example interface for providing a summaries menuon the analyte monitoring device, when the device is in masked mode.History Menu Masked screen 620 is shown provides a menu of summaryoptions that the user can select. Option 620 a takes the user to aLogbook screen for viewing logged data. Option 620 b provides a screenshowing summarizing information related to the use of the reader device.Since the device is in masked mode and does not permit the user fromviewing sensor readings, summary screens related to obtained readingsare also not available.

Example Interface Flows

Application Startup

FIG. 36 illustrates a method 4000 when starting up the RD software,according to one embodiment. At block 4002, the Reader is coupled to aremote processing device, such as the user's computer. At block 4004 itis determined whether the software is installed on the remote processingdevice. If not, then the user is prompted to run an installer filestored on the reader, as shown at block 4006. If the user accepts, adefault browser is launched with the data management software (RDsoftware) install website, as shown at block 4008. The user may elect tostart the installation of the RD software and an installer applicationis downloaded to the remote device to install the complete installerapplication, as shown by blocks 1010 and 1012. The standard operationsystem (OS) installer application is run and the RD software islaunched, as shown at block 4012 and 4014.

Referring back to block 4004, if the RD software is already installed onthe remote device, then it is determined if the RD software is currentlyrunning. If so, then the user is taken to the Reader Landing screen atblock 4026.

If the RD software is not currently running, then it is determined if anauto-launch is enabled to automatically launch the RD software if theanalyte monitoring device is coupled to the remote device, as shown atblock 4020. If the auto-launch is enabled, then the RD software islaunched on the remote device. If the auto-launch is not enabled, thenthe user may manually launch the software when desired, as shown atblock 4022.

When the RD software is launched, the software may automatically performor ask to determine if updates to the software are available, asrepresented by block 4034. The RD software may, for example, access aserver via the internet to determine what updates are currentlyavailable, and then compare the version of the software and any previousupdates to see if any additional updates are missing. If new updates arenot available, then the RD software application continues with the DataManagement Startup process to enable the user to use the RD software, asrepresented at block 4036.

If new updates are available, then the Reader Landing screen isdisplayed, as shown at block 4026. If the user elects not to run theupdate routines at this time, the RD software application continues withthe Data Management Startup process to enable the user to use the RDsoftware, as represented at block 4036. If the user elects to installthe updates, then the update routines are run, as shown at block 4024,before continuing on with the Data Management Startup process at block4036

If instead of starting at block 4002, the user launches RD softwarealready installed on a remote device, as shown at block 4028, then it isdetermined if the analyte monitoring device is coupled to the remotedevice, as shown at block 4030. If the reader device is not connected,then a Reader Welcome screen is displayed to assist the user as the RDsoftware is running, as shown at block 4032. If the reader is coupled tothe remote device, then it is determined if any updates are available asshown and discussed for block 4034.

As the RD software starts up, it isdetermined if there is date (e.g., sensor readings) on the readerdevice, as shown at block 4042. If there is no data on the readerdevice, then it is determined if the reader device has already been setup, as shown at block 4044. If not, then the user is taken to a GuidedReader Setup—Welcome screen for guiding the user through the readersetup process, as shown at block 4046. If the reader device has beensetup before, then it is determined if the reader device and remotedevice are out of sync (e.g., the time on the Reader device and theremote device are different) If the reader device is out of sync, then aReader Out of Sync screen is provided, as shown at block 4052, to informthe user and to enable synchronization. If the reader device is not outof sync, then the Reader Landing Screen is displayed, as shown at block4050.

Referring back to block 4042, if sensor reading data is on the readerdevice, then the data may be downloaded to the remote device, eitherautomatically or upon user confirmation, as shown by block 4054. Atblock 4054, it is determined if the reader device and remote device areout of sync. If so, then the Reader Out of Sync screen is displayed. Ifno out of sync, then it is determined if it is the first time creatingreports on the remote device, as shown at block 4058, If so, then aGuided Reports Setup—Welcome screen is displayed, as shown at block4060, to assist the user with setting up reports. If it is not the firsttime creating reports on the remote device, then it is determined if aquick print feature is enabled to allow quick display and/or printing ofpredetermined or pre-customized reports. If the quick printing featureis not enabled, then the user is taken to a Generate Reports screen toenable the user to generate reports, as shown at block 4068.

Insulin Calculator Setup Interface:

An exemplary embodiment of a graphical user interface which may beutilized in connection with Health Management Software for a Reader asdescribed herein and which facilitates a procedure for inputting theinsulin calculator settings via the Health Management Software isprovided. This graphical user interface is now described in greaterdetail with reference to FIGS. 43-46 .

In some cases, the Health Management Software for the Reader may includeprogramming for two or more types of medication dosage calculators.During setup of the Health Management Software, the Health ManagementSoftware may prompt the user and/or the health care professional toselect a type of medication dosage calculator (e.g., insulin boluscalculator). The initial selection of the type of medication dosagecalculator may be changed as desired by the user or the health careprofessional. In certain embodiments, the two or more types ofmedication dosage calculators include two types of bolus calculators.For instance, the two types of bolus calculators can include an easybolus calculator and an advanced bolus calculator.

By “easy calculator”, “easy bolus calculator”, “simple boluscalculator”, “easy insulin calculator” or “simple insulin calculator” ismeant a bolus calculator that includes basic features for determining arecommended medication dosage amount, such as a recommended insulindosage amount. For example, an easy bolus calculator may includealgorithms configured to determine a recommended medication dosageamount based on a fixed medication dosage amount. In these instances,the easy bolus calculator may be appropriate for a user that administersa fixed medication dosage amount (e.g., a fixed insulin dosage amount)for each meal. In some embodiments, the easy bolus calculator only takesinto account the fixed medication dosage amount when recommending themedication dosage amount to the user, and thus functions as a reminderand/or log for the fixed medication dosage amount.

The insulin calculator setup procedure begins on the Insulin CalculatorInterface Setup screen 3800, where the user can select an InsulinCalculator On/Off toggle button 3802 to turn the insulin calculator onor off. When the Insulin Calculator On/Off toggle button is selectedinto the “On” position, the insulin calculator is activated and may beset up as described below. The desired type of insulin calculator (e.g.,easy or advanced calculator) can be selected by selecting the insulincalculator selection box 3804, which allows the selection of “Easy” toactivate the easy insulin calculator, and “Advanced” to activate theadvanced insulin calculator.

If the user selects the “Easy” selection in the insulin calculatorselection box 3804, the Insulin Calculator Setup Interface screen 3800displays the set up options for the easy bolus calculator. Set up forthe easy bolus calculator is shown in FIG. 43 .

In certain embodiments, the easy bolus calculator may determine arecommended medication dosage amount (e.g., a recommended rapid-actinginsulin dosage amount) based on information, such as, but not limitedto, a fixed medication dosage amount, a target blood glucose range(e.g., correction target), and an insulin sensitivity (e.g., correctionfactor). In some instances, the easy bolus calculator may also includeinformation, such as the patient's insulin on board, in thedetermination of a recommended medication dosage amount. For example, afixed medication dosage amount may be entered by meal (e.g., breakfast,lunch and dinner).

The Insulin Calculator Setup Interface screen 3800 includes amount entryboxes for each meal. A fixed medication dosage amount may be enteredinto the breakfast amount entry box 3806, the lunch amount entry box3808 and the dinner amount entry box 3810 as units of insulin. In someembodiments, the correction target range may be entered. The InsulinCalculator Setup Interface screen 3800 includes correction target rangeamount entry boxes for the minimum target range value 3812 and themaximum target range value 3814. In some embodiments, the InsulinCalculator Setup Interface screen 3800 includes a correction factoramount entry box 3816 in which the insulin sensitivity (e.g., correctionfactor) may be entered as 1 unit per X mg/dL, where X is the amountentered for the correction factor. In some embodiments, the InsulinCalculator Setup Interface screen 3800 includes radio buttons forenabling or disabling insulin calculator trend correction by selectingeither the trend correction enabled radio button 3818 or the trendcorrection disabled radio button 3820, respectively.

If the user selects the “Advanced” selection in the insulin calculatorselection box 3824, the Insulin Calculator Setup Interface screen 3822displays the set up options for the advanced bolus calculator. Set upfor the advanced bolus calculator is shown in FIG. 44 , which showsadvanced bolus calculator settings available when the insulin calculatoris set to count carbs by grams of carbs.

By “advanced calculator”, “advanced bolus calculator” or “advancedinsulin calculator” is meant a bolus calculator that includes additionalinformation, such as, but not limited to, the amount of carbohydratesconsumed, the carbohydrate ratio, a target blood glucose range (e.g.,correction target), and an insulin sensitivity (e.g., correctionfactor), in determining a recommended medication dosage amount (e.g., arecommended insulin dosage amount). For example, rather than using afixed medication dosage amount for each meal as in the easy calculator,the advanced bolus calculator may use dose determination informationentered by the user, such as the amount of carbohydrates consumed, todetermine a recommended medication dosage amount. The advanced boluscalculator may also include additional dose determination informationinto the determination of the recommended medication dosage amount, suchas but not limited to, a patient's the current blood glucose level, anamount of exercise, a target analyte concentration (e.g., a target bloodglucose range), an insulin sensitivity (e.g., correction factor), aduration of insulin action, a carbohydrate ratio, and insulin on boardinformation, such as an administered medication dose time information,an administered dose frequency information over a predetermined timeperiod, and an administered medication dose amount.

The Insulin Calculator Setup Interface screen 3822 includes an “EnterFood By” selection box 3826, which, when selected, allows the user toset the insulin calculator to enter food by grams of carbs or byservings. If “Grams of Carbs” is selected in the “Enter Food By”selection box 3826, then Insulin Calculator Setup Interface screen 3822displays the set up options for the advanced bolus calculator by gramsof carbs.

In some embodiments, the carbohydrate ratio may be entered. The InsulinCalculator Setup Interface screen 3822 includes a carbohydrate ratioamount entry box 3828 for entering the amount of the user's carbohydrateratio as 1 unit per X grams of carbs, where X is the amount entered. Insome embodiments, the correction target range may be entered. TheInsulin Calculator Setup Interface screen 3822 includes correctiontarget range amount entry boxes for the minimum target range value 3832and the maximum target range value 3834. In some instances, thecorrection target may be entered as a single target value rather than atarget range by selecting “Single Target” (not shown) from thecorrection target selection box 3830. In some embodiments, the InsulinCalculator Setup Interface screen 3822 includes a correction factoramount entry box 3836 in which the insulin sensitivity (e.g., correctionfactor) may be entered as 1 unit per X mg/dL, where X is the amountentered for the correction factor. In some embodiments, the InsulinCalculator Setup Interface screen 3822 includes radio buttons forenabling or disabling insulin calculator trend correction by selectingeither the trend correction enabled radio button 3838 or the trendcorrection disabled radio button 3840, respectively.

As shown, Masked Mode setup screen 5090 provides a section5092 in which the user can activate the Masked Mode and set reminders tocheck glucose at preset intervals. For example, the reminder is resetevery time the sensor is scanned. As shown, the menu 5058 of triggerelements for initiating various screens is maintained in the Profilescreen 5086.

Reset System:

The Professional Options screen also enables the user reset settings ofthe Reader device. The Reset System interface may permit reset of allsettings at once, and/or permit the user to selectively reset specificsetting on the device.

Referring back to FIG. 39 , at block 4094, the user is taken to aBackups screen where the user can save a backup file of a current Readersetting. In one embodiment, the backup files do not save glucose resultsor other Reader logbook entries.

Thus, from the menu 5058 of trigger elements for initiating variousReader Mode screens, which remains on the various Reader Mode screens toenable quick reference and access to those screens, the user is able tonavigate to the desired Reader Mode screen. Once the settings areviewed, edited, or deleted, the user can save the setting to the reader,as shown by reference path X3. At block 4096, a Reader Status screen isdisplayed to indicate to the user that a save is in progress. In block4098, a Progress screen is shown to indicate a save to the reader, andafter the save the user is taken to a Reader Landing—Settings savedscreen to indicate that the save was successful, as shown by block 4100.

If changes to any settings in menu 5058 are cancelled, as shown byreference path Y3, or the user navigates away, as shown by referencepath A4, then the user is taken to a warming Alert screen to alert theuser that changes will be lost, as shown at 4102 via reference path Z3.If changes are cancelled, then the user is navigated back to the ReaderLanding screen 4082. If the user elects to save the changes, then toblocks 4096 and 4098 as previous described. If the user elects to notsave the settings, then the user is taken to the Reader Landing—Settingsaved screen 4100.

From the Backups screen, the user can save a backup file, as shown atblock 4104. Progress screen 4106 is displayed while the save is inprogress. If the save should be cancelled before complete, then the useris taken back to the Backups screen 4108.

If the save is determined to be not valid, as shown at block 4105, thenthe user is taken to an Alert screen 4110 to indicate to the user that asave is not valid. For example, if the filename already exists, then theuser can elect to either save it and overwrite the previous file, andwill be taken to the Progress screen 4106. If the user elects not tosave it, then the user is then back to the Backups screen 4112.

From the Backups screen at block 4094, the user can select a backup fileto restore, as shown by block 4114 and reference path C4. Once thebackup file is selected the user is taken to a Progress screen 4116 thatindicates that the backup file is being processed. If the processing ofthe backup file is determined to not be valid or encounters an error,then the Alert screen 4120 is displayed to indicate that there was anerror with the backup file (e.g., that the file is damaged). The user isthen taken back to the Backups screen, as shown by block 4122. If theprocessing of the backup file is valid, then the Restore Reader Settingis displayed to indicate that the Reader settings are being restored tothe settings on the backup file. If the restore should be cancelled,then the user is taken back to the Backups screen, as shown by block4126. If the restore is not cancelled, then the user is taken to eithera Reader Status screen 4128, or to a Progress screen 4130 and Backupsscreen 4132, similarly as described above.

Out of Sync Flow

FIG. 48 illustrates a method 5100 for a flow for syncing the Readerdevice when the Reader is coupled to the remote device and determined tobe out of sync with the remote device. For example, when out of sync,the time on the Reader is different than the time on the remote device.

If the Reader is coupled to the remote device and determined to be outof sync with the remote device, then the Reader Out of Sync screen at5102 is initiated, as shown by block 5102. An Alert screen is displayedto alert the user of the sync and ask if the user wishes to synch theReader with the remote device. The user is also taken to the Alertscreen at 5106 from the General Reader Settings screen when it isdetermined that the two devices are out of sync, as shown by block 5104.

If the user elects to sync the two devices, then a Reader Status screenat 5108 and Progress screen at 5110 are displayed while the update is inprogress. When the update is complete, the user is taken back to theReader Landing—Reader updated screen, as shown at block 5112.

Guided Reader Setup Flow

When a new Reader that has never been used is connected to the remotedevice, the user is guided through the initial setup of that Reader in astep-by-step fashion. Along the way, basic Reader configuration settingssuch as name, patient ID, date, time, and language are collected for thepurpose of initializing the Reader. In one embodiment, the patient nameand ID are optional settings while the date, time, and language optionsmust be set to complete the setup process.

FIG. 49 illustrates a method 5100 for a flow for the Guided Reader Setupinterface, according to one embodiment. When a new Reader that has neverbeen used is connected to the remote device, the New Reader Welcomescreen is displayed to start the guided setup process, as shown at block5116.

The first time a user accesses the printing features of the application,they are guided through the reports setup and creation process in astep-by-step fashion by a Guided Reports Setup interface. Along the way,the RD software collects default reports preferences such as patientinformation, timeframe, report set, glucose targets, and auto-saveoptions, as well as prepares the first set of reports for viewing,saving, and printing.

FIG. 55 illustrates a flowchart for a Guided Reports Setup interface,according to one embodiment. The first time a user accesses the printingfeatures of the application, user is taken to the First-Use ReportsWelcome screen to begin the guided setup. The Start/Patient info screenis initiated to receive patient info, as shown at block 5182. Then theuser is navigated through the following screens: Timeframe screen atblock 5186 to enable the user to establish default timeframes used whenreports are generated; Set Reports screen at block 5188 enable the userto pre-select reports to be generated each time the user generatesreports with the data management software; Glucose Targets screen atblock 5190 to enable the user to establish the default setting for theglucose target range and hypoglycemia threshold to be applied togenerated reports; Auto-Save Options screen at block 5192 to enable theuser to activate and set the auto save feature, as well as, choose thefile name format, and save location that will used during reportcreation; and Ready to Generate Reports screen at block 5194 whichallows the user to generate the selected reports and either view them orprint them.

When printing the selected reports, the Progress screen at block 5196 isdisplayed while the report is being generated. When complete, the Viewreports screen at block 5198 displays the generated report, or providesa menu to select from various reports generated. The Reports are thenimmediately printed via a Print window screen at block 5200. If autosave is set, once the reports are generated at block 5196, the selectedreports are automatically saved to the selected destination, as shown atblock 5204. If the creation at block 5196 is interrupted or cancelled,then the user is taken back to the Generate Reports screen at block5202.

When electing to view the selected reports form block 5194, the Progressscreen at block 5206 is displayed while the report is being generated.When complete, the View reports screen at block 5210 displays thegenerated report, or provides a menu to select from various reportsgenerated. If auto save is set, once the reports are generated at block5206, the selected reports are automatically saved to the selecteddestination, as shown at block 5204. If the creation at block 5206 isinterrupted or cancelled, then the user is taken back to the GenerateReports screen at block 5208.

Export Reader Flow

The RD software provides a function for users to export data from aReader coupled to the computer as a tab-delimited file or otherspreadsheet-compatible format, for example. The Export function may beaccessed, for example, via the “File” menu of the application.

FIG. 56 illustrates a method for exporting Reader data, according to oneembodiment. At block 5252 of Export Meter Data interface 5250, it isdetermined if the Reader device is coupled to the remote device. If notcoupled, then the Export data feature is disabled (e.g., in the Filemenu) as shown at block 4254. If the Reader device is coupled to theremote device, then it is determined if the Reader device has sensordata stored, as shown at block 5256. If the Reader has no data stored,then the Export data feature is disabled at block 4254. If the Readerdoes have data, then it is determined if the Reader is downloading data.If so, then the Export data feature is disabled at block 4254. If theReader is not downloading data, then the Export data feature is enabled(e.g., in the File menu).

Once enabled, the user can select to export data from the Reader, asrepresented by block 5262. Once selected, the meter export file is savedas shown at block 5264. If the save is determined to be valid, then theProgress screen 5272 is shown to indicate that the process of exportingdata is in progress. If no error occurs, the user is taken back to theoriginating screen as shown at block 5276. If an error occurs, an Alertscreen is provided to notify the user of the failed export, as shown atblock 5274.

If at block 5266, it is determined that the saving of the meter exportfile was not valid, then an Alert screen is provided to notify that thesave was not valid (e.g., the file already exists), as shown at block5268. The user is provided with the option to overwrite the existingfile, which navigates the user to the Progress screen at block 5272. Theuser is also provided the option to not save the invalid file, in whichcase the user is taken back to the originating screen, as shown at block5270.

Reports
